Definitions
- the present invention relates to a device which is intended for joining together belt elements, preferably toothed belt elements and which comprises a first flat part having a surface for abutment with one side of an end-part of a first belt element and a surface for abutment with the one side of an end-part of a second belt element, and further comprises a second flat part having a surface for abutment with the other side of the end-part of the first belt element and a surface for abutment with the other side of the end-part of the second belt element.
- Toothed belt elements have previously been joined to ⁇ gether with the aid of butt-straps or plates of particu ⁇ lar configuration which are overlapped on mutually adjacent end-parts of the toothed belts and the ends of the toothed belts securely clamped between the straps or plates and fixed with the aid of screws.
- the ends of the belts are glued togeth ⁇ er, one end of the belt being placed in a recess in the other end of the belt.
- An object of the present invention is to provide a belt- joining device which will enable two toothed belt ele ⁇ ments to be joined together quickly and simply without the use of additional fastener means.
- a belt-joining device of the aforedescribed kind which is characterized in that the two flat parts are mutually joined by a hinge which permits one flat part to be folded over the other; in that in each case one of these belt abutment surfaces of the flat parts which oppose one another subsequent to folding said flat parts presents at least one outwardly- projecting engagement element whose cross-section corre ⁇ sponds generally to the cross-section of a recess in respective ends of the belt elements; and in that the two flat parts are provided with coacting snap-lock means which function to mutually lock said flat parts and hold the end-parts of the belt elements firmly clamped between the flat parts with the engagement elements inserted in respective recesses.
- This construc ⁇ tion of an inventive belt-joining device enables the belt ends to be readily placed on one flat part and the other flat part then folded over the belt ends with respective engagement elements moved into engagement with associated recesses in the belt ends, said snap ⁇ lock means being caused to mutually lock the flat parts with the belt ends clamped therebetween, without the need of additional fastener means, such as screws, glue, etc.
- the flat parts can be folded either along, a line which extends in the length direction of the belt ele ⁇ ments or along a line which extends transversely to said length direction.
- the hinge has the form of a thinned web-part between the flat parts, wherein when folding is to be effected along a line which extends transversely to the length direc ⁇ tion of the belt elements, a throughlet opening is provided for the insertion of one belt element in said web-part.
- One flat part is preferably provided with a transverse abutment element whose one side forms an abutment for the end-edge of one belt element while the other side forms an abutment for the end-edge of the other belt element.
- the belt element engagement means preferably has the form of rack teeth and, when the belt elements have mutually different widths, have a length which corre ⁇ sponds to the length of respective teeth on the belt elements.
- the snap-lock means may have any desired appropriate form.
- the snap ⁇ lock means may have the form of two projections formed on one of the flat parts, these projections being in ⁇ tended for insertion into corresponding recesses in the other flat part, wherein outwardly projecting members on one side of the abutment elements are intended to snap into corresponding apertures in the projections.
- the inventive belt-joining device is advantageously produced from plastic material in a single-piece struc ⁇ ture.
- Figure 1 is a perspective view of an inventive belt- joining device and shows the device prior to being fitted;
- Figure 2 illustrates the belt-joining device when fitted in a position of use, in which two toothed belt elements of mutually different widths are held together;
- Figure 3 is a side view of the belt-joining device when fitted.
- the belt-joining device comprises a first flat part 12 which has a support surface 14 for supporting one side of the end-part of a first belt element 16, which in the example illustrated in Figure 2 is comprised of a toothed jalousie-like belt which is intended to cover a gap intended for the read head of a printer unit.
- the flat part 12 also has a support surface 18 for support ⁇ ing one side of the end-part of a second belt element 20, which in the Figure 2 illustration is comprised of a toothed belt which is intended to drive a read head slide (not shown) to the printer unit and which is to be joined to the jalousie-belt 16.
- the end-edges of the belt element 16, 20 are intended to abut a respective side surface of an abutment element 22 which extends transversely across the flat part 12.
- the belt-joining device 10 also includes a second flat part 24 which is joined to the first flat part 12 through the medium of a thinned web-part 26.
- the web- part 26 is provided with a throughlet opening 28 for the narrower toothed belt 20.
- the flat part 24 has a plural- ity of engagement elements in the form of gripping ridges 30 whose cross-sections and lengths correspond to the cross-sections and lengths of the tooth interspaces on the toothed belt 20.
- the flat part 24 also includes a transverse gripping bar 32 which is intended to be inserted in shape-conforming engagement in a space between two rib elements 34 on the first belt element 16 when the second flat part 24 is folded around the web- part 26 and over the first flat part 12 subsequent to having first inserted the toothed belt 20 through the opening 28 and into abutment with the abutment element 22 and subsequent to having placed the jalousie belt 16 on the support surface 14.
- the flat parts 12, 24 are provided with mutually coacting snap-lock members.
- these members may com- prise projections 36 provided with apertures 35 and fitted to the flat part 24, and two recesses 38 which are complementary to the projections 36 and included in the flat part 12, wherein a wedge-shaped outwardly projecting member 40 on one side wall of the abutment element 32 is intended to snap into the aperture 35 of respective projections 36.
- a spring tongue 42 Located on the respective sides of the recesses 38 opposite the wedge-shaped member 40 is a spring tongue 42 which functions to hold the projection 36 in engagement with said wedge-shaped projection 40.
- the inventive belt-joining device is conveniently injec ⁇ tion moulded in the form of a single-piece structure from plastic material, for instance from a polyamide plastic.
- an embodiment is con ⁇ ceivable in which the flat parts are folded over one another through the agency of a web-part which lies on one side of the belt elements, i.e. an embodiment in which the flat parts are folded along a line which extends parallel with the length directions of the belts.
- the throughlet opening for inser ⁇ tion of the toothed belt 20 is not required.
- the gripping ridges and bar 30, 32 may alterna ⁇ tively be located on the support surfaces 14, 18 or on both of the flat parts 12, 24 when the toothed belt has teeth on both sides thereof.
