Definitions

  • the present invention relates to a clamping device and in particular to such a clamping device as consists of two shanks which are connected to each other and are mutuaLLy sprung with the spring bias acting in opposite directions, and a Locking device so arranged as to be capable of being displaced along the shanks in order to adopt one of two positions, being a first position in which the shanks adopt an open or divergent position, and a second position in which the shanks move towards each other in a closed or convergent position, with the Locking device being so arranged as to be capable of being extended and displaced along a rod, one end of which supports the shanks.
  • a clamping device of the present kind may be used in a range of different applications, particular mention shouLd be made of the fact that the clamping device can be speciaLLy adapted to serve as a clothes peg and to hold clothes which have been washed on a clothes Line or washing Line.
  • PreviousLy disclosed is the design of clamping devices, in particular clothes pegs, in which two shanks are so arranged as to interact with each other via a spring.
  • the shanks act as a two-armed Lever about the attachment for the spring and are forced towards each other by the spring.
  • the other ends wiLL open against the spring bias.
  • PreviousLy disclosed is the manufacture of these clothes pegs in wood or plastic.
  • ALso previousLy disclosed via Swedish Patent Specification 133 689 is the manufacture of a cLothes peg in metal with two mutuaLLy sprung and connected shanks, the ends of which are bent inwards between the shanks to form a sprung cLamping device.
  • the clothes peg is so executed for this purpose as to exhibit fastenings directLy opposite each other intended to grip the clothes and the washing Line.
  • the ends of the parts which are bent inwards between the shanks must be supported against the insides of the shanks so as to form sprung and sliding gripping components for the clothes and the washing Line.
  • ALso described is a Locking ring enclosing the shanks of the clothes peg, said Locking ring being so arranged as to be capable of being displaced along the clothes peg and so arranged as to engage in one of a number of Locking grooves formed on the shanks of the clothes peg intended to Lock the shanks securely in the desired position on the washing Line.
  • clamping devices in particular clothes pegs, of the previously disclosed nature consisting of two shanks with interjacent springs, said shanks acting about the spring as a two-armed Lever, exhibit the disadvantage that the shanks twist in relation to each other under uneven Load and become detached from the spring attachment.
  • a clothes peg of the nature described in Swedish Patent Specification 133 689 basically suffers from the disadvantage that it requires the clothes peg to be made of metal, besides which the Locking ring is difficult to move from one Locking groove to another, and it is particularly difficult to achieve this movement using only one hand.
  • clamping devices for example clothes pegs
  • This is particuLarLy true in the sense that causing the clamping device to move into the open position normaLLy caLLs for the application of a considerable amount of force, usually equivalent to or somewhat in excess of the tension of the spring.
  • a further major technical problem is associated with the design of a clamping device such that it may, in a simple, effective and space-saving fashion, be packaged in such a way that the pack containing a number of clamping devices will possess a rectangular configuration.
  • the present invention relates to a clamping device, for example a clothes peg, consisting of two shanks which are connected to each other and are mutuaLLy sprung with the spring bias acting in opposite directions, and a Locking device so arranged as to be capable of being displaced along the shanks in order to adopt one of two positions, being a first position in which the shanks adopt an open or divergent position, and a second position in which the shanks adopt a closed or convergent position, with the Locking device being so arranged as to be capable of being extended and displaced along a rod, one end of which supports the shanks.
  • a clamping device for example a clothes peg, consisting of two shanks which are connected to each other and are mutuaLLy sprung with the spring bias acting in opposite directions
  • a Locking device so arranged as to be capable of being displaced along the shanks in order to adopt one of two positions, being a first position in which the shanks adopt an open or divergent position
  • the invention relates to the novel feature that there is present at the second end of the rod an operating organ which is so arranged as to force the Locking device into the second position against the spring bias of the shanks in a previously disclosed fashion, and that the operating organ exhibits means for Locking the Locking organ in that position.
  • the shanks are executed each with its own sloping surface which match the corresponding sloping surfaces of the Locking device, said sloping surfaces being so dimensioned as to be capable of causing the Locking device to be displaced by the spring bias of the shanks towards the first position.
  • the operating organ is so arranged as to be capable of forcing the Locking organ to be displaced towards the second position, thereby causing the shanks to move graduaLLy towards each other.
  • the operating organ is so attached via a shaft to the other end of the rod as to be free to rotate.
  • ParticuLarLy appropriate to the present invention is the manufacture of the shanks and the rod, the Locking organ and the operating organ from a palstics material, with the preferred plastics material used being polypropylene.
  • the Locking organ and also the operating organ By causing the shanks, the Locking organ and also the operating organ to be given an essentially wedge-shaped form such conditions will be created as will permit the simple and space-saving packing of a number of clamping devices in a rectangular pack (container or box), so that two clamping devices placed side by side will form a parallelepipedic shape, when the operating organs will adopt a position in which the Locking organs will be in their second position and the two clamping devices are positioned in such a way that the respective operating organs each faces in its own particular direction.
  • the advantages which may be regarded as being principally associated with a clamping device in accordance with the present invention are essentiaLLy that the constituent parts can be produced in a simple fashion from a plastics material, that the operation of the clamping device via the operating organ is easy for the disabled and does not call for the use of a great deal of force, and that the clamping device has been so designed as to permit the simple packing of a number of clamping devices into a rectangular pack.
  • a clamping device preferably a clothes peg, 1 consisting of two shanks 2, 3 which are connected to each other and are mutually sprung with the spring bias acting in opposite directions. This is achieved by causing the parts 2a and 3a of the shanks to be separated via a slot 4 and to be connected to each other as indicated by the reference designation 5 via a groove 6 .
  • a Locking organ 7 is so arranged as to be capable of being displaced, amongst other things, along the shanks 2, 3 and in particular the parts 2a and 3a of the shanks in order to adopt one of two positions.
  • a first position is shown in Figure 5, where the shanks 2, 3 adopt an open or divergent position, and a second position is shown in Figure 1, where the shanks adopt a closed or convergent position by being moved closer together. It is proposed in conjunction with the manufacture of the shanks 2, 3 that these should be executed for this purpose with an opening somewhat Larger than that shown in Figure 5.
  • the Locking organ 7 is so arranged as to be caused to adopt the position shown in Figure 5 by the spring bias which the shanks 2, 3 exert on the Locking organ.
  • the Locking organ 7 is so arranged as to be capable of being extended and displaced along a rod 8 , one end of which 8a supports the shanks 2, 3 .
  • an operating organ 9 At the other end 8b of the rod is present an operating organ 9 , said operating organ being so arranged as to be capable of forcing the Locking organ 7 to be displaced against the spring bias of the shanks 2, 3 into the second position, as shown in Figure 1, and of Locking the Locking device 7 and the shanks 2, 3 in that position.
  • the shanks 2, 3 are executed each with its own sloping surface 2b, 3b which match corresponding sloping surfaces in the Locking device 7 and which have been given the reference designations 7a and 7b in Figure 3. These sloping surfaces are so dimensioned as to be capable of causing the Locking device 7 to be displaced by the spring bias of the shanks 2 and 3 towards the first position shown in Figure 5, although in addition the Locking device 7 will be forced to be displaced towards the second position, as shown in Figure 1, as the free ends 2c, 3c of the shanks 2, 3 gradually move towards each other.
  • the operating organ 9 is so attached via a pivot shaft 10 to the other end 8b of the rod 8 as to be free to rotate.
  • the operating organ 9 exhibits an operating rod 9a situated to one side of the pivot shaft 10 , and a heel 9b designed to actuate the Locking organ 7 situated to the other side of the pivot shaft 10 .
  • the heel 9b is so executed as to exhibit chamfering or rounding 9b enabling it to slide into good contact with the end surface 7c of the Locking organ 7 .
  • shanks 2, 3 and the rod 8 and the Locking organ 7 and the operating organ 9 shall be capable of being manufactured from a plastics material.
  • PoLypropyLene is proposed as a suitable plastics material.
  • the clamping device is assumed to adopt the position shown in Figure 5 as a result of the organ 9 having adopted its first position and as a result of the shanks 2, 3 being able to force back the sleeve 7 against the operating organ 9 , it will then be possible to place the open shanks 2 1 and 3' over a washing Line holding items of washing.
  • the operating organ 9 By then causing the operating organ 9 to turn in the direction of the arrow into a position as shown by solid Lines in Figure 1 , said position constituting the second position, the advantage will be provided that the shanks 2 and 3 are caused to interact with each other by moving into the position shown in Figure 1. Any variations in the thickness of the material which is to be held in place can be absorbed by the elastic deformation of the part 7d of the sleeve 7 and to a certain extent also by the shanks 2, 3 themselves.
  • the Locking organ can be manufactured with a material thickness of 0.8 - 1.0 mm, which may also be regarded as being applicable to the rod 8 .
  • the operating rod 9a may be provided with a hole 9a' intended to be capable of interacting with a hook or similar.
  • a second embodiment is shown with reference to Figures 6 and 7. This, too, exhibits two shanks 2, 3 separated by a slot 4 .
  • a Locking organ 7 with a continuously tapering cross-section is capable of being displaced towards, and is capable of being displaced by the tension of the shanks 2, 3 away from the flat surface 2b, 3b of the shanks 2, 3 .
  • These surfaces exhibit recesses 2b', 3b' for the purpose of increasing the size of the opening between the shanks 2, 3 when the Locking organ 7 is in its released position.
  • the operating organ 9 consists in this instance of two components 9d and 9e which interact with each other, said component 9d exhibiting a hook 9f and two pins 9g and a third pin 9h .
  • the pins 9g shall interact with holes 9k in the component 9e , which exhibits a pin 9h' .
  • the pins 9h and 9h' are intended to form a pivot shaft for the organ 9 and shall interact with a hole 11 in the rod 8.
  • acetal resin for instance DeLrin 500.
