The present invention relates to a locking and removable conduit housing" for conduits such as electric wires and cables and water, steam and s p p One of its objects is to provide a housing for the conduits namedwhich may be afiixed like molding to'the wall or to the floor.
iAnother'object isto provide a housing for such conduits; which may be installed without disconnecting the conduits:
A further object is the provision of a housingfor electric wiring which may be acceptable to the fire'underw-riters.
A still further obj'ectis the provision of locking and unlocking means for such housing.
-These and other'objects may be attained by providing a housin comprising four simple parts; abase plate to aflix to the wall or floor; one or more brackets to be afiixed to the plate a channel shaped cover to fit over the brackets; and, a locking stud to engage the brackets through the cover.
Preferred embodiments of the invention: are illustrated in the accompanying drawings in which- Figure 1 is a transverse section of the entire housing, said view beinga view on the line I-I' of Figure 2.
Figure 2 is a longitudinal section of theentire housing, showing how adjoining lengths of the housing are-joined;
Figure 3 is a perspective view of the cover portion of the housing, showing how adjoining lengths thereof are joined;
Figure 4 is a perspective view of the plate portion of the housing, showing the bracket porti0ns,.
also in perspective, affixed thereto.
Figure 5 is a perspective view of the locking stud portion of the housing;
Figure 6 is a section on the line 66 of Figure 1, showing the socket portion of the brackets which receives the locking stud portion;
Figur 7 is a perspective View of said bracket socket portion;
Figure 8 is a transverse section of another em-.
1 to 7 inclusive of the drawings, the housing construction comprises a, base plate I5, a bracket; I6 afiixed'. thereto, a channel shaped cover I1 mounted on said bracket, and a locking stud I8 engaging said bracket through said cover, and locking said cover to said bracket.
Base plate I5 comprises an elongated, rec-tan-' gularshaped body It? made, preferably, of metal, but which may also be made of plastic or any other similar material. Body [9' may be made in any width, length and thickness. It is suggested however, that it be made in varying widths, such as 2, 3, 4 and 5' inchv widths. For certain purpcsesbody- I9 may have a width of a foot and may even be made wider than that. A standard length of- 6 0rd feet is suggested, and a thickness corresponding to the thickness of moderately heavy sheets of sheet metal. Body I9 may have small holes 20- formed in it at spaced intervals. Plate I5 is placed flat against the floor 2| near the wall I (or against the wall near the floor or elsewhere) and aflixed thereto by means of screws 22.
Bracket I6 comprises a substantially U shaped body 2-3 consisting of two' leg portions 24 and 25 joined at one end by means of yoke 25, said leg portions haVi-ng inwardly tred foot portions 21' and 28 at the other end. Foot portions 21 and 3 2-8' liein a common plane which is parallel to the plane inwhich yoke 26 is disposed. Leg portions 24 and-2'5 are parallel to each othe and sub- 30' stantiall y perpendicular to-yoke 28 and foot portions 21 and 28.
Yoke 26 has a circular depression 29 formed in it, approximately midway between leg portions 24'. and 25, said depression having a transverse raised portion 30. In the center of said circular depression 29 and cutting across said raised portion 30, is a substantially rectangular aperture 3|, longitudinallydisposed with respect to the yoke 26.
Bracket I6 may be made either of metal or of plastic material, but preferably of metal having a thickness substantially equal to the thickness of the base plate I5. As is clearly shown in Figures 1 and 4, bracket I6 is affixed transversely to base plate l5, its foot portions 21 and 28 in contact with, and either welded or riveted to said base plate, its leg portions- 24 and 25 lyingin a plane, respectively, with side edges 32 and 33 of said base plate. From this description it is apparent that the length of bracket I6 is substantially-equal to the width of base plate I5. There may be a many brackets 16 to each base plate I5. as may be found desirable. It is suggested that brackets I6 be spaced at intervals of 2 feet.
Channel cover I'I comprises an elongated substantially U shaped body 34 having shape and' dimensions enabling bracket l6 as afiixed to base plate |5 to nest within it. Midway between its legs 35 and 36, and at regular intervals throughout its length (which corresponds to the length of base plate l5) are apertures 31 having downwardly beveled edges 38. Cover apertures 31 are intended to register with bracket apertures 3|. There are therefore at least as many cover apertures 37 as there are brackets |6 and bracket apertures 3 At one end of each length of channel cover I! is a raised, stepped'portion 39 which is intended to receive telescopically the opposite end 40 of an adjoining length of channel cover Channel cover I! may be made either of metal or of plastic material, but preferably of metal.
The same type of sheet metal out of which base plate I 5 is intended to be made, will sufiice for channel cover l1.
Locking stud l8 comprises a beveled head 4| having a screw driver receiving slot 42, a stem portion 43 and a transversely elongated, rectangular base portion 44. Base portion 44 has a beveled end portion 45 and a rounded surface 46 facing the beveled head 4|. l
The beveled head portion 4| corresponds in shape and dimensions to the beveled channel cover apertures 31. The rectangular base portion 44 corresponds in shape and dimensions to.
the bracket apertures 3|. The rounded surface 46 of rectangular base portion 44 corresponds in shape and dimensions to the hollow portion 41 which is formed underneath raised portion 39 of bracket Hi. There are as many locking studs H! as there are brackets Hi and channel cover apertures 31.
The embodiment of the invention shown in Figures 8, 9, 10 and 11 is in all respects identical with the embodiment shown in Figures 1 to '7 inclusive, except in the following particulars:
Base plate 48 as shown in Figures 8 and 10 has upturned and then inwardly turned side edges 49 and 50. Bracket 5| has inwardly turned, and then downwardly turned and then outwardly turned leg ends 52 and 53. The bracket 5| may be made of spring steel. The grooves 54 and 55 which are thus formed in leg ends 52 and 53 are adapted to receive base plate edges 49 and 56. Bracket 5| is afiixed to base plate 48 simply by squeezing leg ends 52 and 53 together and then allowing them to spring outwardly to engage base plate edges 49 and 50.
The invention may be used in the following manner, referring now to the embodiment shown in Figures 1 to '7 inclusive.
The base plate |5 to which brackets |6 are aflixed, is fastened to an appropriate place such as the fioor 2|. Wires or cables 56 are now drawn through brackets I6 and connected in the usual manner. Channel cover I! is then placed over brackets IS in such manner that its legs 35 and36 straddlebrackets l6 and reach floor 2| immediately adjacent both long edges 32 and 33 of base plate |.5. Locking studs l8 are now inserted into and through channel cover apertures 31 and bracket apertures 3 A screw driver is then used to turn locking studs l8 one quarter of a turn until their rounded surfaces 46 fall into hollow'portions 41 of brackets IS. The heads 4| of locking studs |8 will now be flush with the outer surface of channel cover H. The invention is now installed.
The embodiment shown in Figures 8 to 11 inclusive may be installed around wires 56'even thoughthesewires may be fully connected at both ends. This may be done as follows:
Base plate 46 is inserted under wire 56 1ongitudinally with them. It is then fastened to fioor 2| as above described. Brackets 5| are now sprung into, engagement with base plate edges 49 and 50. The channel cover and locking studs are then installed in the manner outlined above. 7
It is apparent that the specific illustration shown has been given by way of illustration and not by way of limitation and that the structure above described is subject to a wide variation and modification without departing from the scope or intent of the invention, all of which variations and modifications are to be included within the scope of the present invention.
