(54) SECURING DEVICE
(71) I, ROBERT ARTHUR HENDERSON hARD, of Church Farm, 63 Church Lane,
Backwell, Bristol, BS19 3JJ, a British Subject, do hereby declare the invention, for which I pray that a patent may be granted to me, and the method by which it is to be performed, to be particularly described in and by the following statement:
This invention relates to devices for securing two bodies together, and more particularly by tightening around one body a strap which is attached to a channel member carried by the other body and having a restricted mouth
In my co-pending British Patent Speciflcation No. 1533412 there is disclosed a device for securing to a post a body provided with a channel member having a restricted mouth, the device comprising an elongate plate for insertion lengthwise into the channel to extend across its mouth and be retained in the channel by the inturned lips thereof, a pair of attachment members connected or arranged for connection to the elongate member through the mouth of the channel and connected or arranged for connection to a strap to be passed around the post.
This device, while being very strong, extremely difficult to force out of the channel, and easy to use on site, has certain disadvantages. The spacing of the attachment members is fixed, so it is necessary to have different sizes of devices for different size posts unless an intermediate saddle is used. The full length insert plate represents a substantial part of the materials cost, and the device requires at least two welds which add to the labour and time costs in manufacture. Also, it is sometimes inconvenient on Site to have a unitary construction of that type for insertion into the channel as a single unit. The present invention seeks to ameliorate some or all (depending on the particular embodiments) of the above disadvantages.
The present invention discloses a modification in which, instead of a single elongate members carrying both attachment members, one or both attachment members are made of rigid sheet material and include separate attachment means comprising a plate part for insertion lengthwise into the channel member to extend across its mouth and be retained therein by the lips of the channel member, and a neck part extending from the plate part through the channel mouth.
This arrangment provides the versatility of separate attachment members which can be inserted from opposite ends of the channel and whose relative positions in the channel member can be optionally located for different sizes of body around which the strap is tightened. The separate relatively short plate parts use less material and yet surprisingly provide sufficient bearing area under the channel lips to give little risk of distortion of the channel. Although the neck part and plate part are both made of sheet material, e.g. stainless steel sheet, so that in theory the union between the parts could bend under the tension of the strap and reduce the bearing area of the plate and channel lips, in practice it has been surprisingly found that this union is very resistant to bending, particularly if the plate extends longitudinally of the channel on each side of the neck part.
The separate attachment members seem to be self-aligning in the channels, thereby minimising distortional forces. Securing devices of this kind made of stainless steel sheet in soft aluminium channels have been found to withstand high loads and strains, for sample in mounting heavy road signs in windy regions.
Various embodiments will be described with reference to the accompanying drawings, wherein:
Fig. 1 shows a cross-sectional view through a post supporting a sign using one embodiment of securing device,
Fig. 2 shows a perspective view of one of the attachment members of Fig. 1,
Fig. 3 shows a perspective view of another embodiment of device for securing a sign to a post, and
Figs. 4 and 5 show perspective views of further embodiments of attachment members.
Referring to Figs. 1 and 2 of the drawings; a sign panel 10 is provided on its rear surface with a channel member 12, made for example of extruded aluminium, and having a rearwardly directed mouth restricted by a pair of inturned lips 14. The sign is mounted to a circular section post 16 by means of a pair of attachment members 18 and a flexible strap 20 of high tensile material, such as stainless steel. The attachment members 18 are also conveniently made of stainless steel sheet. Each attachment member comprises a body part 22 having a slot 24 to receive the strap 20. One end of the body is bent over at 26 to seat against the post 16. From the other end of the body extends a narrower neck 30 which passes through a slot 31 in a rectangular plate 33 and is turned over at right angles at 35 to be welded to the surface of the plate 33 remote from the body part 22. It is preferred that the - end of the neck bt turned over in the same direction as the end of the body part, but it could be turned over in the opposite direction.
In mounting the sign to the post, each attachment member is attached to the channel by inserting the plate into the end of the channel and sliding it lengthwise of the channel until it is in the desired position, the neck 30 extending through the restricted mouth of the channel, and the two turned-over portions 26 being directed towards each other. The strap 20 is then passed through slots 24, the sign is offered up to the post so that the post seats between the turned-over ends 26 of the attachment members, and the ends of the strap are tightened around the post and secured together by a buckle 34 in known manner.
The particular configuration of the attachment members removes any tendency for them to slide towards each other under the tension of the strap, and thereby relax the tension. The strap passing through the apertures 24, pulls the attachment members firmly up against the lips of the channel approximately tangentially to the post and at right-angles to the mouth of the channel. If desired, the strap can be threaded through the attachment members prior to their fitting in the channel.
Although only one channel member and securing device and one post are shown, the sign will usually have more than one channel member, sometimes more than one post, and a corresponding number of securing devices, depending on the size of the sign.
Referring to Fig. 3; the device comprises a strap 52 of U-shaped form, suitably made of stainless steel strip, to be passed around the post. The ends of the strap are cranked at 53 for engagement in slots 55 in the bodies of attachment members 84, 85 respectively. The attachment members are also made of stainless steel sheet. The attachment member 84 is a generally T-shaped form, with a body 88 and a narrower neck 86. The neck 86 passes through a slot 82 in a short rectangular plate 80, and the end of the neck is turned at right-angles to the rest of the attachment member and towards the opposite attachment member 85, and is spot-welded to the underside of the plate 80.
The attachment member 85 is a generally Shaped form, one limb 57 having the slot 55, and the other limb 59 being apertured to take the shank of a bolt 89, which is retained by a nut 91. The end of the limb 59 is downturned to provide a rib 61, which is further extended to provide a central lug 63. The attachment member 85 and its manner of use are more particularly described in my British Patent
Specification No. 1416734. If desired, the cranked end 53 of the strap is spot-welded to the attachment member 85. The other end of the strap, however, is a loose fit in the slot 53 of the attachment member 84, and is retained therein by blips 87 formed in the cranked end of the strap.
Thus, the attachment member 84 is, in effect, hingedly connected to the strap 52.
In use; a number of attachment members of the present invention are fitted to the channel members on the rear of the sign, as described above in relation to Fig.
1. This is effected by introducing the head of the bolt 89 and the plate 80 into the end of the channel, and sliding them along the channel to the desired position for securing to the post. At some stage the attachment member 85 has to be detached from the bolt 89. This can be done before introducing the bolt into the channel, or thereafter just prior to mounting the sign to the post. With the attachment member 85 detached from the bolt, the strap 52 can be hinged relative to the attachment member 84, and when the sign is offered up to the post the strap 52 can be passed around the post and the attachment member 85 once more reattached to the bolt 89 by means of the nut 91. The nut 91 is then tightened to draw the strap tightly around the post. The downturned rib 61 on the attachment member 85 bears upon the lips of the channel member, and the lug 63 engages in the mouth of the channel.
Various modifications are possible within the scope of the present invention. For example, the L-shaped attachment member 85 could be formed as an integral extension of the strap 52. Alternatively, the attachment member 85 could be replaced by a second attachment member 84. In such a case, to provide for the necessary adjustment of the strap, the strap could conveniently be formed in two parts extending from respective attachment members, the ends of the strap parts being drawn around the post and secured together in known manner, for example by a "Band-it" (Trade Mark) or "Tespa" (Trade Mark) buckle. The T-shaped part of the attachment member 84 could, particularly in the modification last described, be formed as an integral extension of the strap, rather than as a separate member.
Figs. 4 and 5 show modified attachment members made from a single piece of sheet steel. In Fig. 4, a rectangular body part 100 has a slot 102 to receive a strap as in the previous embodiments, and carries a narrower neck part 104 to extend through the mouth of the channel member. The far end of the neck carries an enlarged plate part 106 integrally formed therewith and simply bent at right angles to the plane of the neck part. Fig. 5 shows a similar construction except that the portions of the sheet material on either side of the neck which would be cut out in the embodiment of Fig. 4, are left attached to the plate part 106, thereby providing extensions 108 on the other side of the neck part. This may further improve the strength and stability of the device as compared with that of Fig. 4. Instead of a slotted body part to take a separate strap, the body part in the attachment members of
Figs. 4 and 5 could be integral with respective straps which are tightened around the post and secured together at their ends remote from the attachment members.
The plate parts of the present securing devices are preferably somewhat longer than they are wide. This gives increased bearing area under the lips and prevents their being inadvertently inserted into the channel at right-angles to the correct orientation.
