Abstract

A clamp for an aerial bundled cable to be installed on walls of buildings and wood poles in particular, which clamp comprises a strap (6), an installation plug (5) and a body portion (1) provided with an installation groove (2) for the cable and a nail passage (3) provided for a fastening nail of the clamp and extending essentially perpendicularly with respect to the axial direction of the cable. In order to enable installation of the clamp to the supporting structure thereof also in such a manner that the installation groove will be vertically positioned, a second nail passage (4) is provided which extends from the bottom of the installation groove (2) of the body portion (1) through said body portion (1) essentially perpendicularly to said first nail passage (3). The second nail passage (4) advantageously extends through the first nail passage (3). <IMAGE>

Description

SPECIFICATION A clamp especially for an aerial bundled cable The invention relates to a clamp especiallyforan aerial bundledcableto be installed on walls of buildings or on wood poles in particular, said clamp comprising a body portion provided with an installation grooveforthe cable, and a nail passage providedforafastening nail of the clamp and extending essentially perpendicularly with respectto the axial direction of the cable.
Clampsorfastening nails of this type are used for the installation of aerial bundled cables on wall surfaces of buildings or on wood poles when the cable is installed in an essentially horizontal position. Because the nail passage for fastening of the clamp on a supporting structure is in clamps described above positioned essentially perpendicularly with respect to the installation groove of the cable, the nail passage cannot beused for fastening of the clamp if the cable must be installed in an upright position on a wall surface or on the surface of a wood pole.Therefore it is necessary in such cases to use either clamps especially intended for the purpose or clamps of the above type must be provided with special connecting parts by means of which the clamps can be connected to the supporting structure also in such a a mannerthatthe installation groove is vertically positioned.
The object of the present invention is to provide a clamp for an aerial bundled cable, which clamp is adapted for use both when the cable is installed in the normal way, i.e. horizontally, and when the cable must be mounted on the installation surface thereof in an upright position. This is effected in the clamp according to the invention by providing said clamp with a second nail passage which extends from the bottom ofthe installation groove ofthe body portion through the body portion essentially perpendicularly to said first nail passage. lnordertominimizethesize ofthe clamp and the amount of material used for it, it is of advantage that the second nail passage extends through the first nail passage.In orderthatthe head of the installation nail would be positioned ata sufficient distance from the cable when the clamp has been installed in place, it is advantageous that the second nail passage is enlarged attheend thereof adjacent the installation groove ofthe cable at least in level with that surface of the first nail passage which is away from the installation groove of the cable, whereby the head of the installation nail is positioned in level with said surface when the clamp has been mounted in place.
The clamp according to the invention will be more closely described in the following with reference to the attached drawings, wherein Figure 7 is a perspective view of a clamp according to the invention provided with an installation plug and a strap, Figure2 is a side view of the clamp of Figure 1 as a partial longitudinal section.
The clamp shown in Figure 1 comprises a body portion 1, to which an installation plug 5 is mounted, whereby a nail passage 3 extends through the body portion and the plug. One side of the body portion 1 istrough-like, thus providing an installation groove 2 for the cable. For locking of the cable into the installation groove, the clamp is further provided with a strap 6 which, in the embodiment of Figure 1, forms an integral part of the plug 5.
When a clamp ofthetype shown in Figure 1 is installed on a wall surface in the usual way, a hole of suitabie dimensions isfirst bored in thewall, the plug 5 being inserted in said hole. Thereafterthe body portion 1 is attached to the plug 5 as shown in Figure 1 and a nail is driven into the nail passage 3 of the clamp, which nail tends to drive apartthe halves of the plug 5 when it is thrust thereinto, whereby the clamp is firmly fastened to the supporting structure thereof. Thereafter the cable is positioned in the installation groove 2 thereof to be secured in place by means of the strap 6.
If the clamp according to Figure 1 is used in such a mannerthatthe installation groove will be vertically positioned the body portion is fastened on the supporting structure by means of an installation nail passed through the second nail passage 4. The cross-section ofthe clamp shown in Figure 2 illustrates in more detail the structure of the second nail passage 4. It extends from the bottom ofthe installation groove 2 through said bottom 7 and the first nail passage 3. Said second nail passage 4 is enlarged in a portion 15 adjacentthe installation groove 2 in orderthatthe head ofthe installation nail would be positioned at a sufficient distance from the cable positioned in the installation groove 2when the clamp has been installed in place.The cable is attached to the body portion installed on its supporting structure by threading a separate strap (not shown) of a commonly known type through a strap channel 14 extending underthe bottom 7 ofthe installation groove 2 parallel to the nail passage 3.
Such a strap serves also as a coverforthe head of the nail (not shown) driven through the nail passage 4 and as an insulator between the nail head and the cable. Because the head of the installation nail positioned in the second nail passage 4will be positioned in level with a bottom surface 13, said nail does not, either, prevent passing of the strap through thestrapchannel 14.
It should be mentioned that the strap 6 shown in Figure 1 is, when a body portion 1 according to Figure 2 is used, adjustable between two degrees of tightness by positioning it either in an opening 8 of the installation groove 2 or in an opening 9. If a conventional strap is used in connection with the clamp according to the invention, a cable of a very small cross-sectional area can be fixed in place simply by passing the strap only around the bottom 7 of the installation groove 2. Correspondingly, a cable or a bundleofcablesofafairlylarge cross-sectional area can be fixed in place by passing the retaineraroundthe bottom and ribs 10 and 11 defining the edges of the installation groove 2.
Figure 2 fu rther illustrates a cover 12 which closes the first nail passage in such a mannerthatthe head of a fastening nail possible mounted therein can be covered from the surroundings thereof.
The clamp according to the invention for installation especially of an aerial bundled cable has been described above only by means of one specific embodiment and it is to be understood that it can be modified in various ways without, however, deviating from the scope of protection defined in the attached claims. So the second nail passage could be positioned also atthe side ofthe installation groove 2 in such a mannerthatitdoes notextendthrough the first nail passage 3. However, such a structure would increase consumption of material to some extent, wherefore it could be regarded as less advantageous. Also other previously known alternative structures of particularly the installation groove 2,the retainer 6 and the plug 5 and other related elements thereof can be used with the clamp according to the invention.

Claims (6)

1. Aclamp especiallyforan aerial bundled cable to be installed on walls of buildings orwood poles in particular, said clamp comprising a strap and a body portion provided with an installation grooveforthe cable, a firstnail passage for a fastening nail of the clamp and extending substantially perpendicularly with respect to the axial direction ofthe cable, and a second nail passage extending from the bottom of the installation groove ofthe body portion through said body portion substantially perpendicularly to said first nail passage.
