Description

The invention relates to an adapter for fastening a pipe clamp to a rail with the features of the preamble of claim 1.

In generic adapters, the attachment of the pipe clamp on the adapter via a first bayonet closure. The attachment of the adapter together with mounted pipe clamp to the rail via a second bayonet lock. Both bayonet locks are formed on the adapter. The problem with this is that the first bayonet closure, which acts on an upper side of a main body of the adapter at this, requires a very specific thickness of the base body. Although the attachment can be done without tools, all pipe clamps that should be used with such an adapter, but must have a body with this thickness. A universal applicability of the adapter regardless of the thickness of the body of the clamp is not given.

The object of the invention is to provide a generic - preferably tool-usable - adapter, which is universally applicable.

This object is achieved by an adapter with the features of claim 1. Advantageous embodiments of the invention are defined in the dependent claims.

Due to the fact that the fastening device has at least one clamp which can be inserted into an opening arranged on the pipe clamp and holds the pipe clamp on the adapter in the assembled state, one and the same adapter can be used with pipe clamps with different thickness base bodies, since it is for fixing the Pipe clip on the adapter is not required that a part of the adapter engages around the base body, but the clip is in the regardless of the thickness of the body always placeable in the same place opening (which may be designed as a slot, for example) introduced. A tool-free use is possible as in the prior art.

The clip has a bridge and a tongue protruding from the bridge. Insert the clamp with the tongue into the opening on the clamp. The length of the web (between a base of the adapter and the tongue) is chosen so that the tongue is at the height of the opening when the pipe clamp rests against the base body of the adapter. The tongue is hinged to the web or the web is hinged to a base of the adapter (preferably each via a flexure). Such an articulated connection allows a certain mobility of the tongue when inserted into the pipe clamp arranged on the opening.

Preferably, a locking device for detecting a free end of the clip (possibly the tongue of the clip) is provided relative to the adapter. This is a backup of the clip against unintentional release relative to a main body of the adapter is possible when the pipe clamp is connected to the adapter. The locking device may be formed as a latching lug or as a, in an opening disposed at the free end of the bracket opening, mandrel may be formed. It can be arranged on the locking device at least one driver, through which in an assembled state of the pipe clamp on the adapter a force exerted on the pipe clamp torque on the adapter is transferable. This prevents twisting of the clamp relative to the adapter. It is envisaged that the fixing device of the adapter is designed as a bayonet closure, wherein an actuation of the bayonet closure on the application of a rotational force on the pipe clamp, the at least one driver prevents unintentional opening of the locking device by the rotational force, because the rotational force on the driver of the Locking device (eg., In a main body of the adapter) is transferable.

In one exemplary embodiment of the invention, it is provided that the clamp has a centering projection (for example a knob) which can be inserted into a recess arranged on the pipe clamp. This allows automatic centering of the clamp on the bracket of the adapter regardless of a width of the clamp.

In one embodiment of the invention it is provided that a positioning aid for the pipe clamp is arranged on a base body of the adapter. This allows a correct positioning of the pre-positioned on the clamp pipe clamp on the base body of the adapter.

In one embodiment of the invention it is provided that the fixing device for fixing the adapter to the rail has a bayonet closure. In this case, the connection of the clamp with the adapter can be made via a sliding movement and the connection of the adapter together with fixed pipe clamp to the rail via a rotary motion. Thus, different types of movement are provided for the attachment of the clamp on the adapter on the one hand and the attachment of the adapter to the rail on the other hand.

It can be provided that the adapter is formed in one piece and is preferably made of a plastic. Alternatively, especially for the provision of a higher load capacity Formation of the adapter made of a metal possible. A one-piece design of the adapter is also possible in this case, but preferably there is a separate production and subsequent connection of the fixing device and the remaining parts of the adapter.

In one embodiment of the invention, it is provided that the adapter has a base body and at least one stop for the pipe clamp is arranged on that side of the base body on which the pipe clamp rests in the assembled state. By means of the at least one stop, a rotational force applied to the adapter by means of the pipe clamp can be transmitted to the fixing device, which is particularly advantageous when the fixing device has a bayonet closure.

Protection is also desired for an arrangement with an adapter according to at least one of the above-described embodiments and a pipe clamp having an opening, wherein the clip of the adapter is inserted into the opening and holds the pipe clamp on the adapter.

It is preferably provided that the opening is arranged on a base body of the pipe clamp. The opening may be formed as a passage opening.
