Abstract
Description
- The invention relates to a device for opening an oyster, comprising an oyster support for supporting the oyster, an opening element holder which is arranged so that it is movable in its longitudinal direction and in one opening element holder end thereof comprises an opening element, a drive handle for driving the opening element holder, which drive handle comprises a first and second handle end, is pivotably connected by the first handle end thereof to a fixed point of rotation and between the first and second handle end is connected to the opening element holder and a supporting element for supporting the opening element holder and the drive handle.
- Such a device is disclosed in
US patent 3,151,352 . In order to open an oyster, the oyster is placed in the correct position against the oyster support. The drive handle is then moved manually towards the oyster support, so that the opening element holder moves in the direction of the oyster until the opening element comes into contact with the oyster. From this position the drive handle is moved with a powerful movement in the direction of the oyster support for the actual opening of the oyster. - Oysters by their nature have different dimensions. These dimensions can vary between 5 and 20 cm. As a result of this, with oysters of different dimensions and in the situation described above where the opening element makes contact with the oyster, the drive handle in the known device is in different positions relative to the opening element holder. This means that the drive handle is often not in the position in which the greatest possible power transmission to the opening element holder is achieved. The user consequently has to exert unnecessarily great force on the drive handle. Since such devices are often used for opening large quantities of oysters, it is very important for the opening to proceed with as little physical effort as possible from the user, in order to prevent injuries.
- An aim of the invention is to provide a device for opening oysters in which optimum power transmission from the drive handle to the opening element holder is obtained. This aim is achieved in that the support element is adjustable relative to the oyster support, the device comprises guide means for guiding the adjustable support element in the direction of movement of the opening element holder, and in that the support element comprises fixing means for fixing the support element on the guide means. The effect of this is that the distance between the support element and the oyster support can be adjusted. This means that with the different dimensions of the oysters the support element can be fixed in such a position on the guide means that in the situation described above where the opening element makes contact with an oyster a line extending through the point of rotation and through the second handle end is positioned perpendicularly to the direction of movement of the opening element holder. The greatest power transmission of the drive handle to the opening element holder is achieved in this position. It enables the user to open an oyster with the least possible physical effort.
- In one embodiment of the device according to the invention the guide means comprise a first and a second guide, the first and second guides being located at a distance from each other. This has the advantageous effect that a very stable construction of the device is produced. It is also advantageous in the situation where the device according to the invention comprises an electric drive motor for the drive, instead of a drive handle. The first and second guides can extend substantially parallel to each other and in the direction of the oyster support. The first and second guides can be bar-shaped.
- In one embodiment according to the invention the device comprises positioning means connected to the guide means, which positioning means extend away from the guide means in such a way that when the device is placed on a flat surface in such a way that the positioning means make contact with the flat surface the support element is located at a distance from the flat surface. In the position for use the oyster opener is placed on a flat work-surface. Owing to the fact that the positioning means ensure that in the position for use the support element does not make contact with the work-surface, the work-surface does not constitute an obstacle to the movement of the support element along the guide means when the device is in this position. This means that the distance between the support element and the oyster support can be adjusted without it being necessary to lift the device off the work-surface. This makes the device considerably easier to use.
- In one embodiment the support element comprises a fixing handle for controlling the fixing means and, measured in the direction of movement of the opening element holder, the fixing handle is located at a greater distance than the opening element from the oyster support. This specific positioning of the fixing handle means that the user does not have to place his hands in the path of the opening element in order to adjust the position of the support element. This is important for increasing the safety of the user at the time of adjustment of the position of the support element.
- The guide means can comprise markings and the support element can comprise a viewing aperture for making it possible to see markings covered by the support element. Oysters sold on the market are usually sorted by size. The oysters on sale are grouped into various groups, all oysters of a group being approximately of the same size. Virtually all oyster sellers on the market use the same measurements for grouping oysters. By placing the markings in such a position on the guide means that the support element is at an optimum position for a certain group when a marking is visible through the viewing aperture, the user can place the support element quickly in the correct position for a certain group.
- Oysters sold on the market are often divided into four groups. In one embodiment according to the invention the fixing means are therefore arranged in such a way that the support element can be fixed in four specific places on the guide means. The distance between these four specific places can be 6 cm. In the situation where a line extending through the point of rotation and through the second handle end is positioned perpendicularly to the direction of movement of the opening element holder the distance between the opening element and the oyster support in those four specific positions of the support element can be 6, 12, 18 and 22 cm.
- In one embodiment according to the invention the device comprises liquid collection means for collecting liquid from an oyster to be opened, and the liquid collection means comprise a filter element for filtering the liquid collected. Liquid is released during the opening of an oyster. This liquid is very tasty. Collecting it means that this liquid can be put back in the opened oyster again. The filter element is preferably positioned in such a way that the released liquid is filtered before it is collected by the collection means. In this way a direct separation is achieved between the liquid and the grit released from the oyster shell when it is opened. This is important for minimising the taste transfer between the grit and the liquid. The filter element can comprise a fine-mesh gauze.
- The oyster support can comprise a stop element of elastic material. By means of this elastic material, preferably rubber, a good grip of the oyster on the oyster support is obtained, and during the opening of the oyster the side of it which is in contact with the oyster support is less damaged.
- In one embodiment according to the invention the guide means comprise first recesses and the fixing means comprise a rotary rod interacting with the first recesses, which rotary rod comprises a second recess for guiding the support element along the guide means. In this way the user is able to fix the support element on or disconnect it from the guide means by a single turning movement exerted upon the fixing handle.
- The invention furthermore relates to a method for opening an oyster, which method comprises the steps of positioning an oyster against an oyster support, positioning a support element - which support element is adjustable along guide means and comprises a drive handle and an opening element which is movable in the longitudinal direction - in such a position that the opening element is placed against the oyster and the drive handle is in the position in which a maximum power transmission to the opening element is obtained, fixing the support element in that position on the guide means, and moving the drive handle in order to open the oyster with the opening element.
- The invention will be explained in greater detail with reference to the drawings, in which:
