Description

Description [0001] 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 pipe clamp is usually attached to the adapter via a first bayonet catch. The adapter and the attached pipe clamp are attached to the rail using a second bayonet lock. Both bayonet locks are formed on the adapter. The problem with this is that the first bayonet catch, which engages on an upper side of a base body of the adapter, requires a very specific thickness of the base body. The attachment can be done without tools, but all pipe clips that are to be used with such an adapter must have a base body with this thickness.

Furthermore, a modular support system for pipes is known from US 2010/0155545 A1. The pipe clamp and adapter are connected by means of projections on the side of a base body of a pipe clamp, which engage with recesses of an adapter, the adapter at least enclosing the base body of the pipe clamp. Again, tool-free attachment is possible, but here too, all pipe clamps require a base body with a thickness designed for the adapter to be used.

The US 5,680,680 A is a clamp for attaching non-structural elements such as insulation mats or bundles of cables to be found on structural elements. A clamp is arranged so that it at least partially encloses a structural element. A c-shaped bracket ensures that the clamp cannot be detached from the structural element by vibrations or the like. However, such a clamp developed for use in aircraft is not suitable for fastening a pipe clamp to a conventional rail. In addition, an additional part - the c-shaped bracket is required to install this clamp.

Is a device for tool-free attachment of a light bulb to a gutter is shown. A first part of the device is attached to a rain gutter by means of a clip, a second part, which has a receptacle for a light bulb, can be connected to the first part. It is also not possible to attach a pipe clamp to a conventional rail using this device.

A universal applicability of the adapter regardless of the thickness of the base body of the pipe clamp and / or the usability with conventional rails is not given in adapters according to the above prior art.

The object of the invention is to provide a generic - preferably usable without tools - adapter, which is more universal.

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

Characterized in that the fastening device has at least one bracket which can be inserted into an opening arranged on the pipe clamp and holds the pipe clamp in the assembled state on the adapter, one and the same adapter can be used for pipe clamps with different thicknesses of base bodies, since it is for it is not necessary to attach the pipe clamp to the adapter so that part of the adapter engages around the base body, rather the clip is inserted into the opening (which can be designed as a slot, for example), which can always be placed at the same point regardless of the thickness of the base body , Tool-free use is possible as in the prior art.

The clip has a web and a tongue protruding from the web. The tongue must be inserted into the opening in the pipe clamp. The length of the web (between a base body of the adapter and the tongue) is chosen so that / 13

AT518 987 B1 2018-03-15 Austrian patent office the tongue is at the height of the opening when the pipe clamp lies against the base body of the adapter. The tongue is articulated to the web or the web is articulated to a base body of the adapter (in each case preferably via a flexible joint). Such an articulated connection allows a certain mobility of the tongue when inserted into the opening arranged on the pipe clamp.

Preferably, a locking device for locking a free end of the clip (possibly the tongue of the clip) is provided relative to the adapter. This makes it possible to secure the clip against unintentional loosening relative to a base body of the adapter if the pipe clamp is connected to the adapter. The locking device can be designed as a locking lug or as a mandrel that can be inserted into an opening arranged at the free end of the clamp. At least one driver can be arranged on the locking device, by means of which a torque exerted on the pipe clamp can be transmitted to the adapter in an assembled state of the pipe clamp on the adapter. This prevents the pipe clamp from twisting relative to the adapter. If it is provided that the fixing device of the adapter is designed as a bayonet lock, wherein the bayonet lock is actuated by applying a torque to the pipe clamp, the at least one driver prevents the locking device from being opened unintentionally by the torque, because the torque via the driver from the Locking device (z. B. in a base body of the adapter) is transferable.

In one embodiment of the invention it is provided that the clip has a centering projection (z. B. knob) which can be inserted into a recess arranged on the pipe clamp. This allows an automatic central alignment of the pipe clamp on the clamp of the adapter regardless of the width of the pipe 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 permits correct positioning of the pipe clamp pre-positioned on the 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 lock. In this case, the connection of the pipe clamp to the adapter can take place by means of a sliding movement and the connection of the adapter together with the attached pipe clamp to the rail can be carried out by means of a rotary movement. Thus, different types of movement are provided for attaching the pipe clamp to the adapter on the one hand and attaching the adapter to the rail on the other.

It can be provided that the adapter is formed in one piece and is preferably made of a plastic. Alternatively, the adapter can be made from a metal, in particular to provide a higher load capacity. A one-piece design of the adapter is also possible in this case, but a separate production and subsequent connection of the fixing device and the remaining parts of the adapter are preferred.

In one embodiment of the invention it is provided that the adapter has a base body and at least one stop for the tube clamp is arranged on that side of the base body on which the pipe clamp rests in the assembled state. The at least one stop allows a torque applied to the adapter by means of the pipe clamp to be transmitted to the fixing device, which is particularly advantageous if the fixing device has a bayonet catch.

Protection is also sought for an arrangement with an adapter according to at least one of the above-described embodiments and an opening having a pipe clamp, the clamp of the adapter being inserted into the opening and holding 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 can be designed as a through opening.

AT518 987 B1 2018-03-15 Austrian Patent Office [0019] Exemplary embodiments of the invention are discussed on the basis of the figures. Show it:

1 [0021] FIG. 2 [0022] FIG. 3 an embodiment of an adapter according to the invention in an isometric view, the embodiment of FIG. 1 in a further isometric view, the embodiment of FIG. 1 in a side view [0023] 4a, 4b a pipe clamp in two different isometric views [0024] FIGS. 5a, 5b an arrangement with a pipe clamp and the embodiment according to FIGS. 1 to 3 and FIG. 4 in a state of prepositioning the pipe clamp on the adapter or the attachment of the pipe clamp to the adapter. FIGS. 6a-c variants of the embodiment shown in FIGS. 1 to 3. FIGS. 1 to 3 show an adapter 1 with a base body 8, on which a clamp is on one side 4 of a fastening device for fastening a pipe clamp 2 to the adapter 1 is arranged. On the other side of the base body 8 there is a bayonet lock 9 of a fixing device which has two wings 91 and by means of which the adapter 1 can be fixed to a rail 3. In the exemplary embodiment shown, the adapter 1 is formed in one piece.

In the exemplary embodiment shown, the clamp 4 has a web 41 arranged on the base body 8, on which a tongue 42 is mounted in an articulated manner about an axis parallel to the base body 8 via a bending joint 43. The free end of the tongue 42 of the clamp 4 can be secured against movement away from the base body 8 by means of a locking device. The locking device has a locking lug 5 which engages behind the tongue 42 when it is aligned approximately parallel to the base body 8. In order to allow movement of the tongue 42 from an open position into this position, the latching nose 5 can be pressed out of the way by the tongue 42 during a movement towards the base body 8. In order to design this evasive movement of the locking lug 5 in a defined manner, it can be provided that the locking lug 5 is connected in an articulated manner to the base body 8 via a flexible joint 15.

4a and 4b show a known pipe clamp 2 with a base body 7, two wings 21 for receiving a tube, an opening 6 arranged in the base body 7, a recess 16 for a positioning aid 12 of the adapter 1 and a recess 10 for a centering projection of the adapter 1.

A pipe clamp 2 can be fastened to a rail 3 using an adapter 1 according to the invention as follows:

Preferably the pipe clamp 2 is first attached to the adapter 1. For this purpose, the pipe clamp 2 is pre-positioned on the adapter 1 in such a way that the tongue 42 of the clamp 4 is inserted into the opening 6 arranged here on the base body 7 of the pipe clamp 2 (cf. FIG. 5a). The opening 6 is designed as a through opening, so that the tongue 42 can be guided completely through the opening 6 and with its free end protrudes beyond the base body 7 of the pipe clamp 2.

Because the clamp 4 on its side facing away from the base body 8 has a centering projection 11 which can be inserted into a recess 10 arranged on the pipe clamp 2, an automatic central alignment of the pipe clamp 2 on the clamp 4 of the adapter 1 takes place independently of one Width of the pipe clamp 2.

After the pipe clamp 2 has been pushed onto the clamp 4, the clamp 4 together with the pipe clamp 2 can be pivoted in the direction of the base body 8 by exerting pressure on the pipe clamp 2 or the clamp 4. The free end of the clamp 4 pushes the latch 5 out of the way until the tongue 42 of the clamp 4 is in a position approximately parallel to the base body 8. The locking lug 5 snaps back and prevents the tongue 42 from being moved away unintentionally from the base body 8 (cf. FIG. 5b). Around the tongue

3.13

AT518 987 B1 2018-03-15 Austrian patent office to solve, the locking lug 5 can be manually pivoted away from the tongue 42 until the locking lug 5 releases the tongue 42.

It can be seen that a positioning aid 12 for the pipe clamp 2 is arranged on the base body 8 of the adapter 1. This permits correct positioning of the pipe clamp 2 pre-positioned on the clamp 4 on the base body 8 of the adapter 1. In the exemplary embodiment shown, the positioning aid 12 is so strongly projecting that it moves the tongue 42 of the clamp 4 into the approximately horizontal to the base body 8 of the Adapters 1 aligned position allowed only when the positioning aid 12 is completely received in the recess 16 provided on the pipe clamp 2.

On the locking device, a driver 13 is arranged, through which, in an assembled state of the pipe clamp 2 on the adapter 1, a torque exerted on the pipe clamp 2 can be transmitted to the adapter 1. Unlike shown (driver 13 only on one side of the latch 5), such drivers 13 can also be provided on both sides of the latch 5.

On that side of the base body 8, on which the pipe clamp 2 rests in the assembled state, two stops 14 for the pipe clamp 2 are arranged in the embodiment shown, which are designed here as rails. A torque applied to the adapter 1 by means of the pipe clamp 2 can be transmitted to the fixing device by stops, which is particularly advantageous if the fixing device has a bayonet catch 9.

Now the arrangement of adapter 1 and the pipe clamp 2 connected to it can be fastened to the rail 3 by inserting the adapter 1 into the rail 3 or with its base body 8 on the rail 3 so that the wing 91 of the bayonet lock 9 parallel to the direction of the rail channel. The arrangement is then rotated via the pipe clamp 2, which acts as a lever until the wings 91 of the bayonet catch 9 of the adapter 1 engage behind the walls of the rail channel. Of course, another type of connection of the arrangement to the rail 3 (e.g. via a screw connection) would also be conceivable.

Fig. 6a shows an alternative embodiment of the fixing device of the adapter 1 (this is only shown in the area of its base body 8, but can be designed as shown in Figs. 1 and 2) as a snap connection with two spring hooks 18, which move resiliently when inserted into the rail 3 and thus permit insertion and, in the inserted state, engage behind an inner wall of the rail channel.

6b shows a further alternative embodiment of the fixing device of the adapter 1 (this is only shown in the area of its base body 8, but can be designed as shown in FIGS. 1 and 2) as a screw connection with a on the base body 8 attached or formed threaded pin 19, which can be screwed to a thread-like, here disc-shaped abutment 20.

Fig. 6c shows an alternative embodiment of the locking device for the clip 4 of the adapter 1 (this is only shown in the area of its base body 8, but can be designed as shown in Figs. 1 and 2). The tongue 42 has an opening in which a mandrel 17 can be inserted. In the state inserted into the opening, the mandrel 17 prevents the tongue 42 from moving away from the base body 8 of the adapter 1.
