Abstract

The device for throwing a roll of securing strapping over a load on a lorry platform involves a holder maintaining the roll in an upright position during throwing, protecting it against strong wind. The holder is fitted on a lever arm which gives strength in the throwing process and maintains it at the right height to eject the roll and cause it to unwind over the load.

Description

10 15 20 25 517 438 2 Hållaren (3) kan utföras i olika material t ex. plast, lättmetall, tunn rostfri plåt eller bockad tråd, av vilka plast kanske inte är så bra då det har sämre hållfasthet mot åverkan och omväxlande temperaturer. Det viktiga i konstruktionen är att spännbandsrullen (l) inte åker bakåt när användaren gör sin bakätrörelse med hävarmen (4), 'och att den inte åker lrarnåtförrän kaströrelsen är avslutad. Detta åstadkoms med ett bakre stöd vars hindrande kant måste vara en bit över spännbandsrullens ( 1) centrumlinje, och ett frontstöd vars hindrande kant skall vara strax under centrumlinjen. Hållaren (3) skall även ha två sidostöd för att hålla spännbandsrullen upprätt utan att för den skull hindra dessrörligliet -ocli ett bottenstöd som i sin tur fästes antingen i ett snabbfaste så man lätt kan byta hållaren (3), eller fast direkt på hävarmen (4). Sidostöden bör ”inte vara höge än nödvändigt för att fullgöra sin ﬁinktion, allt för att hålla vikten nere. 10 15 20 25 517 438 2 The holder (3) can be made of different materials e.g. plastic, light metal, thin stainless steel sheet metal or bent wire, of which plastic may not be as good as it has worse resistance to damage and varying temperatures. The important thing in the design is that the strap roller (l) does not go backwards when the user makes its rearward movement with the lever (4), 'and that it does not travel until the throwing motion is completed. This is achieved with a rear support whose obstruction edge must be a bit above the center line of the tensioning roller (1), and a front support whose obstructing edge shall be just below the center line. The holder (3) shall also have two side supports to keep the tensioning roller upright without for that reason, its tube ligament -ocli prevents a bottom support which in turn is attached either in a quick release so you can easily change the holder (3), or fixed directly on the lever (4). The side supports should “not be higher than necessary to fulfill their ﬁ function, all to keep the weight down.

Efter att lasten är på plats behöver man ofta rätta till spännbanden eller dra ner dem ﬁån överbyggnaden (2). För att underlätta detta kan man på baksidan av hållaren (3) montera en hake (5) som i öppningen skall vara något bredare än spärmbandet, så slipper man klättra på ﬂaket eller lasten i onödan och riskera halk- eller fallskador. Alternativt kan man montera haken i nedre änden av hävannen (4).After the load is in place, you often need to adjust the straps or pull down them ﬁ from the superstructure (2). To facilitate this, you can on on the back of the holder (3) mount a hook (5) which should be in the opening slightly wider than the sperm band, so you do not have to climb on the ket bag or load unnecessarily and risk slipping or falling injuries. Alternatively, you can mount the hook at the lower end of the lever (4).

Hävarmen (4) kan vara i ett stycke med anpassad längd efter användaren, men då man ibland kan behöva stå på ﬂaket eller på någon lastbrygga och utföra kasten, kan en delbar eller i längdriktningen justerbar hävarm (4) vara att föredra. Materialet bör vara av lättmetall för viktens skull.The lever (4) can be in one piece with adapted length according to the user, but then you may sometimes need to stand on the eller aket or on some loading dock and perform the throw, a divisible or longitudinally adjustable lever (4) be preferable. The material should be of light metal for the sake of weight.

Då det ﬁrms risk för deformation av översta delen av hävarmen (4) vid ofrivilliga slag mot kanten av överbyggnaden (2) kan man skydda denna med något elastiskt stötdärnpande material en dryg halvmeter närmast hållaren (3). _When there is a risk of deformation of the upper part of the lever (4) at involuntary blows to the edge of the superstructure (2) can be protected with some elastic shock-absorbing material about half a meter closer the holder (3). _

Claims

10 15 20 25 517 438 o: u »- PATENTKRAV

Device for throwing a tensioning roller (1) over a superstructured (2) truck axle and trailer or directly over a load or arm that needs to be fastened with a tensioning strap, characterized by a holder (3) for the tensioning roller (1) which is mounted with a quick coupling or fixed mounting on a fixed or longitudinally adjustable and divisible lever (4) in which the thrower uses, and in that the holder (3) consists of a bottom support and a support in the rear edge which prevents the strap mill (1) from falling out during the rearward movement, and a front support so high that the tensioning roller (1) does not roll forward before the projection ends, and that the holder (3) has two side supports with a distance between each other 'which hold the tensioning roller (1) upright without preventing roll-up during the throw. in

Device according to claim 1, characterized by the retainer (in the rear edge) has a hook device (5) with the aid of which the strap can be pulled down or adjusted before sunbathing. in

Device according to claim 1. Characterized by the fact that a hook device (5) instead of on the rear edge of the holder (3) is placed on the lower end of the lever (4).

Device according to claim 1, 2 or 3, characterized in that a piece of the upper part of the lever (4) is covered with an elastic shock-absorbing material to prevent defects from occurring if the lever (4) strikes load or superstructure at the projection (2) .
