Description

LINE RETAINER DEVICE
FIELD OF THE INVENTION The invention relates to a line retainer device according to the preamble of claim 1.
BACKGROUND TO THE INVENTION AND PRIOR ART
Heavy trucks and buses are examples of heavy vehicles provided with various lines (conduits), e.g. hoses for air and liquid and cables for electricity and fibre optic cables, for transfer of gases, liquids, electric current and electric or light signals between various units in the vehicle.
Fitting a lengthy line in for example a vehicle involves the substantial operation of not only connecting the ends of the line to the various units but also suspending the line relative to the vehicle along the extent of the line so that it will not hang loose and unprotected and thereby be more readily subject to external influences or to risk that movements of the loosely hanging line might cause it to become detached from a unit to which it is connected, which suspension may for example be effected by using plastic binding tape which surrounds the line and a hose bracket fitted to a vehicle part or by fastening a retainer to the vehicle and thereafter placing the line in the retainer.
US 2 108 347 A refers to a pipe retainer for a vehicle, which is adapted to being fastened therein and in which it is thereafter possible to place a pipe.
SUMMARY OF THE INVENTION
The object of the present invention is to propose, e.g. for a vehicle, a line retainer device adapted to making it possible to suspend quickly, easily, safely and in a directionally stable manner at least one line unit comprising at least two lines which run alongside one another, can be held together and diverge. The object indicated above is achieved according to the invention by a line retainer device according to the characterising part of claim 1. A line retainer device which comprises at least one frame and at least two retainer means according to the characterising part of claim 1 which protrude from the frame has the characteristics that a line unit is adapted to being insertable in gaps between the frame and the retainer means, said retainer means having recesses for the line unit, affords the advantage of a line retainer device adapted to making it possible to suspend quickly, easily, safely and in a directionally stable manner at least one line unit comprising at least two lines which run alongside one another, can be held together and diverge.
According to an embodiment of the invention, the free ends of at least one retainer means are adapted to being resilient.
According to a further embodiment of the invention, the frame is of curved configuration resulting in at least one air gap between it and the substrate so that the line unit can be suspended via the line retainer device on a warm substrate without the line unit becoming overheated.
BRIEF LIST OF DRAWINGS
The invention is explained below in more detail with reference to the attached drawings, in which:
Fig. 1 is a schematic view of a first embodiment of a line retainer device according to the invention,
Fig. 2 depicts schematically line units fitted in a line retainer device according to the invention, Fig. 3 is a schematic view of the line retainer device according to Fig. 1 as seen
substantially from above with reference to Fig. 1, Fig. 4 is a schematic view corresponding to that in Fig. 3 of a further embodiment of a line retainer device according to the invention, and
Fig. 5 is a schematic view of the line retainer device according to Fig. 1 as seen substantially from the right with reference to Fig. 1.
DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION
As also indicated by the brief description above of the drawings, the term "lines" in this patent application comprises lines for liquids such as hydraulic lines, e.g. hydraulic hoses, and lines for gases such as pneumatic lines, e.g. pneumatic hoses, and lines for electric current such as electric lines, e.g. electric cables, and fibre optic lines such as fibre cables, e.g. for signalling by means of light. As indicated above, the definition of lines further comprises both flexible lines such as various hoses and cables, and rigid lines such as copper pipes. The definition of lines comprises also tubular protective envelopes such as "Slemmer hoses" in which one or more lines of the previously mentioned kinds may be arranged to run.
The invention is exemplified below by a line unit comprising two lines, viz. a liquid line and an electric line placed in a protective envelope, but the line retainer device according to the invention may be used for two or more lines, i.e. for at least two lines which run alongside one another, can be held together and diverge.
Fig. 1 is a schematic view of a first embodiment of a line retainer device 2 according to the invention which comprises a frame 4 and at least two retainer means 6, 8 which protrude from the frame. The frame 4 forms in combination with a first retainer means 6 a line retainer 10 which has a line space 12 between the frame 4 and the retainer means 6. The retainer means 6, 8 are preferably integral with the frame 4, to which end the line retainer device may for example be stamped from a piece of sheet metal if the frame 4 and the retainer means 6, 8 are made of metal, or may for example be moulded integrally if the frame 4 and the retainer means 6, 8 are made of plastic or metal, making it possible to confine the subsequent machining to drilling to create any fastening holes, and/or to bending of the sheet metal. Alternatively, at least one retainer means 6, 8 may be a separate unit adapted to being fastened to the frame 4 by adhesive bonding, welding, snap- locking, screwing together, riveting or the like.
As mentioned above, the line retainer device 2 may be provided with at least one fastening hole 14, 16 if it is intended to be fitted to a substrate such as a vehicle, e.g. a vehicle frame, by means of at least one fastening means such as screws, rivets or the like, as described in more detail below, but the line retainer device is preferably provided with at least two fastening holes 14, 16 if it is intended to be fitted to a substrate by means of fastening means such as screws, rivets or the like in order to achieve greater assurance of directional stability for the fitted line retainer device 2. Alternatively, the line retainer device 2 may be fitted to a substrate by, for example, adhesive bonding or welding, depending on what material the frame 4 is made of.
As illustrated in the diagram, each retainer means 6, 8 has a free end 20, 22 situated at a distance from the frame 4 so that at least one line unit (depicted in Fig. 2) can be inserted in the gap 24 formed between the frame 4 and the free end 20 of the first retainer means 6, and then into the line space 12 in the line retainer device 2. To achieve directionally stable suspension of the line unit, the second retainer means 8 is disposed in such a way that a further gap 26 is formed between a side edge 28 of the first retainer means 6 and the free end 22 of the second retainer means 8, in which gap 26 the line unit may also be inserted, which side edge 28 of the first retainer means 6 has recesses 30, 32 for at least one line unit, and said free end 22 of the second retainer means 8 has recesses 34, 36 for at least one line unit, affording the advantage of a line retainer device 2 adapted to making it possible to suspend quickly, easily, safely and in a directionally stable manner at least one line unit comprising at least two lines which run alongside one another, can be held together and diverge.
The line space 12 is preferably of such a size, i.e. such a depth A, that the lines do not push apart the frame 4 and the free end 20 of the first retainer means 6 when the line is placed in the line space 12.
Preferably, at least one of the retainer means 6, 8 comprising recesses 30, 32; 34, 36 is arranged to be resilient so that the portions 28, 22 of the retainer means 6, 8 provided with recesses are adapted to springing away from one another when a line unit is inserted through the gap 26 situated between them and to springing back towards one another when said line unit has been placed in the respective recesses 30, 32; 34, 36, in order to keep the line unit in place in the line retainer device 2 so that it is prevented from moving out of the line retainer device 2 by sole force of gravity.
Fig. 2 depicts schematically a line retainer device 2 for at least one line unit 38, 40 comprising at least two lines 42, 44 which run alongside one another and are capable of being held together and a line housing 46 for said lines 42, 44, which line retainer device 2 is arranged to be fittable to a substrate. As mentioned above, the line retainer device 2 comprises a frame 4 and at least two retainer means 6, 8 which protrude from the frame and each have a free end 20, 22 situated at a distance from the frame 4 to make it possible for at least one line unit 38, 40 to be inserted into the gap 24 between the frame 4 and the free end 20 of the first retainer means 6, the second retainer means 8 is arranged in such a way that a further gap 26 is formed between a side edge 28 of the first retainer means 6 and the free end 22 of the second retainer means 8, into which gap 26 it is also possible for the line unit 38, 40 to be inserted, and said side edge 28 of the first retainer means 6 and the said free end 22 of the second retainer means 8 have respective recesses 30, 32; 34, 36 for the line unit 38, 40, resulting in rapid, simple, directionally stable and safe suspension of at least one line unit 38, 40.
According to a preferred embodiment, the line unit 38, 40 comprises two lines 42, 44 which may for example be a liquid line 42 intended for urea to be injected into a silencer of a vehicle in order to achieve low nitrogen oxide contents in the vehicle's exhaust gases, and preferably so arranged that the urea which is returned to a urea tank also cools the urea injection portion of the silencer, and an electric line 44 in the form of a heating coil running spirally round the liquid line to prevent the urea from freezing at low
temperatures, e.g. temperatures lower than about -10°C. According to this embodiment, the lines 42, 44 are two lines running alongside one another and capable of being held together by being arranged to run through a protective envelope 48 until they reach the line housing 46, and diverge at the line retainer device 2. The lines 42, 44 being placed in the line housing 46 as above affords the advantage of a line retainer device 2 which allows rapid, easy, directionally stable and safe suspension of at least one line unit 38, 40 comprising at least two lines 42, 44 which run alongside one another, are capable of being held together and diverge, since it is possible, by respectively snapping the line housing 46 into place in recesses 30, 32; 34, 36 in the line retainer device 2 and snapping the line housing 46 free from recesses 30, 32; 34, 26 in the line retainer device 2, to suspend and release the line unit 38, 40 with the lines 42, 44 from the line retainer device 2.
As illustrated in the diagram, the line space 12 is open on the sides where the lines 42, 44 in their fitted position are intended to pass through it. Preferably any of recesses 30, 32; 34, 36, preferably recesses of the first retainer means 6, may be made so deep that the line unit 38, 40, when in place in the recess, does not bottom in it, making it easier to fit and remove the line unit 38, 40 in the line retainer device 2.
A line housing 46 is preferably adapted to being accommodated in at least one recess 30, 32; 34, 36 of the retainer means 6, 8, preferably in a recess 30, 32 of the first retainer means 6.
Fig. 3 is a schematic view of the line retainer device 2 according to Fig. 1 as seen substantially from above with reference to Fig. 1, depicting the frame 4, the retainer means 6, 8, a gap 28 between the frame 4 and a first retainer means 6 and corresponding line space 12, a gap 26 between a side edge 28 of the first retainer means 6 and the free end 22 of the second retainer means 8, and recesses 30, 32; 34, 36 in the line retainer device 2 for lines. Fig. 4 is a schematic view corresponding to that in Fig. 3 of a further embodiment of a line retainer device 2 according to the invention, depicting the frame 4, the retainer means 6, 8, a gap 28 between the frame 4 and a first retainer means 6 and corresponding line space 12, a gap 26 between a side edge 28 of the first retainer means 6 and the free end 22 of the second retainer means 8, and recesses 30, 32; 34, 36 in the line retainer device 2 for lines.
As illustrated in Figures 3 and 4, the general shape of the frame and the retainer means is not crucial, since the retainer means are provided with recesses which fix the lines with directional stability and preferably releasably in the line retainer device. Since the lines diverge at the line retainer device, the divergence angle achieves directional stability solely as a result of the respective recess of each line in its respective retainer means. A further advantage is that a line retainer device according to the invention may be fitted in any desired orientation in the space without the lines becoming detached from the line retainer device by sole force of gravity, this being made possible by the aforesaid snap- locking.
Fig. 5 is a schematic view of the line retainer device 2 according to Fig. 1 as seen substantially from the right with reference to Fig. 1, depicting the frame 4, the retainer means 6, 8, a gap 28 between the frame 4 and a first retainer means 6 and corresponding line space 12, a gap 26 between a side edge 28 of the first retainer means 6 and the free end 22 of the second retainer means 8, with a further feature in this embodiment that the frame 4 is of angled configuration resulting in at least one air gap 50 between it and the substrate 18, making it possible for the line unit to be suspended via the line retainer device 2 on a warm substrate 18, e.g. a silencer or an exhaust pipe, without the line unit becoming overheated. If further air gaps are desired, a further air gap may be provided by making the recesses in the second retainer means so shallow that an air gap is formed between the lines and the frame 4. The line housing may be of various kinds. For example, at least one line may be arranged to run through the line housing, and/or at least one line may be connected to a duct in the line housing without the line itself running all the way through the duct as in an adapter.
The frame 4 and the retainer means 6, 8 may be integral or be separate elements fastened to one another. Parts from different embodiments may be combined with one another.
The invention is thus in no way confined to the embodiments described but may be varied freely within the scopes of the claims.
