Description
FIELD OF THE :tNVENTION
The present invention relates -to a connector or hub ror use in -the suction like of what is commonly referred to as a central vacuum system and including integrally formed means for holding the low voltage electrical wire of the central vacuum system running along the vacuum suction line.
BACKGROUND OF THE INVENTION
Central vacuum systems, i.e. vacuum sys-tems including an in situ vacuum canister with a series of vacuum inlets located at different locations in a house or a building are becoming ever more popular. In the central vacuum system, the canister is connected -to the inlet through a vacuum line consisting of a number of sections of piping of various lengths and configurations joined together by hubs or connectors. All such systems use a standard low voltage switching circuit to enable the system to be activated and deactivated remotely by the insertion or removal of the flexible vacuum hose into the wall inlet plate.
The low voltage switching circuit as described above uses a low voltage electric wire which, in a standard set up, runs along the vacuum line. According to conventional methods of installation, the low voltage wire is located in position through the use of electrical tape wrapped by the installer around both the vacuum line and ~0 the wire, or in the alternative the installer uses a ~$
~'~5B~
1 separate tie which must be fitted during -the time of installation around and securing the wire to the vacuum line.
Each of the above methods of effectively attaching the wire to -the vacuum line requires that the installer either has the tape immediately available and must take the time -to wrap it around both the wire and the vacuum line or that the installer carry with him a number of ties to be added separately to the vacuum line. This is both time consuming and awkward to work with since both the tape and the tie must be wound completely around the vacuum line where in some locations along its length the line is tightly fitted against a wall or the like making it very inaccessible to the installer.
SUMMARY OF THE PRESENT INVENTION
The present invention provides an answer to the problems described above. In particular, the present invention provides a fitting for an in place vacuum suction line having a low voltage electrical wire running along the suction line. The fitting itself is wi-th wire retaining means formed as an integral part of the fitting for holding the electrical wire to the suction line.
~s~
1 Through the use of the fitting of the present invention, with its in-tegral wire retaining means, there is no need for the installer to carry or Fit -to the suction line additional componen-ts such as tape or ties.
The above as well as other advantages and features of the present invention will be described in greater detail according to the preferred embodiments of the present invention in which:
Figure 1 is a perspective view showing a central vacuum system including a vacuum canister and an in place vacuum line including fittings provided with electrical wire retaining means according to preferred embodiments of the present invention.

DETAILED DESCRIPTION ACCORDING TO THE PREFERRED
EMBODIMENTS OF THE PRESENT INVENTION IN WHICH:
Figure l shows a central vacuum system consisting of a vacuum canister l which produces the vacuum suction for the system. The motor in the canister operates on a normal house current and voltage and uses a low voltage electrical wire 5 (actually housing the two electrical wires as seen in Figure l) which runs along the suction line generally indicated at 7 to a typical wall outlet 3.
The circuit between the canister and the outlet is closed for operating the canis-ter through the insertion of a vacuum hose (not shown) into wall outlet 3.
The vacuum suction line 7 is as shown in Figure l formed with a plurality of pipe sections forming a main suction line as well as branch suction lines such as that running to wall outlet 3. These suction lines consist of various sections of straight piping of dif~erent lengths which are connected together using clamps and connectors known in the trade as hubs. Figures 2, 4, 5 and 7show different types of hubs.
In particular, Figure 2 shows a relatively standard connector or hub 9 u'sed to connect in line straight pipe sections. Connector 9 is provided with electrical wire retaining means in the form of a pair of wire clips lO one at each end of the connector. Each of ~'~5~
SJ-7081-~7 - 5 - 0527B/007~B
1 these wire cllps has a triangulated generally yoke shaped configuration extendlng radially outwardly from the connector as will be clearly seen in Figure 2 the two wire clips are axially aligned with one another along the length of the connector.
From a manufacturing standpoint, connec-tor 9 as well as the pipe sections forming the vacuum suction line are made from a high durability plastic material. The wire clips 10 which are made during the manufacture of the connector comprise the same high durability plastic material and form an in-tegral part of the connector.
Figures 4 and 5 show further preferred embodiment connectors indicated at 11 and 16 respectively. Connector 11 is as seen in Figure 1 used to connect the main vacuum suction line with the branch line and accordingly includes a straight body section 12 and a branching body section 14. For appropriate fitting of the pipe sections into the fitting body section 12 is provided with increased diameter end por-tions 12a and body section 14 is provided with an increased end portion 14a. Each of the end portions 12a is in turn provided with a wire clip 13 while end portion 14a is provided with a wire clip 15. Again it is to be noted that the wire clips 13 are axially aligned with one ano-ther while wire clip 15 is on the same side of the fitting which as shown in Figure 1 is the upper side of the fitting as the wire clips 13. This ensures that all of the wire clips on the main line to branch fitting 11 are easily accessible to the installer.
SJ 70~ 7 - 6 - 0527BJ0073B
1 Fitting 16 is a curved hub used to connect pipe sections at 90 degrees to one another as agaln seen in Figure 1. This hub includes enlarged diameter end regions 16a each of which is provided with a wire clip 17. The two wire clips consistent with the earlier embodiment are on the same side of the hub making them both accessible to the installer.
Figure 7 shows, rather than a connector, a hose clamp 19 having a wire clip 21. The clamp is used along the vacuum line to secure an extended length of pipe to a supporting wall surface or the like.
The construc-tion of the wire clips themselves consistent for all of -the embodiments is well seen in Figures 3 through 5 of the drawings. As no-ted above, the wire clip has a triangular yoke-like shape and is provided with a round undercut portion into which the wire actually fits and an inwardly angled mouth opening to that undercut portion. The inward angling of the mouth provides for a guided snap fitting of the wire into the undercut region.
In the Figure 4 and 5 hub arrangements the placement of the wire clips on the enlarged open mouth end regions provides an effective reducing of the hub at opposite sides of the wire clip further adding to the ease with which the wire can be snapped into the clip, i.e.
there is in effect a recess immediately beside the clip allowing the wire to be pushed down into the recess and into the clip.
In the case of the shorter connector 9 this recess effect for easing snapping of the wire into the clip is provided by the straight pipe sections themselves which as seen in Figure 6 are of reduced outside diameter relative to the connector providing a recess to allow a l'~S~
SJ-70~ 7 - 7 - 0527B/0073B
1 pushing down o~ the wire and snapping it into the wire retaininy clip.
In the case of the clamp 19, it fits to the outside of the pipe section as shown in Figure 7 so that there is again a recessing affect on either side of the clamp.
It will now be appreciated from the description above how the installer aligns the low vol-tage wire along the vacuum line and slmply presses the wire down in-to the clips at each end of the hubs. The undercut configuration of the clips provides a positive locking action on the wire which is easily fitted into the clip both because of the angled mouth as well as the resiliency of the body of the wire itself. This arrangement totally eliminates the need for separate wrap around type ties or electrical tape both of which, as noted above, are very difficult to install particularly at relatively inaccessible areas along the vacuum line.
Although various preferred embodimer-ts of the invention have been described in detail, it will be appreciated that variations may be made without departing from the spirit of the invention or the scope of the appended claims.
