ARRANGEMENT FOR A DOOR

Abstract: The present invention relates to an arrangement for a door intended, in conjunction with the closing of same, to prevent injury by crushing between the door leaf (4) and the case (2). The arrangement (1) comprises a body component (5) with a plane surface (7) intended to be mounted against the door leaf (4). A longitudinal locking component (6) is pivotally mounted in the body component (5). A spring (9) acts between the aforementioned body and locking components (5, 6), which have devices which define a relative angular position. This means essentially that the direction of longitudinal extension of the locking component (6) forms a normal to the plane surface (7) of the body component (5). The spring (9) forces the components (5, 6) to adopt the aforementioned angular position. The body component (5) with the locking component (6) mounted in it is intended to be mounted on the inside of the door leaf (4) in a position such that, as the door is opened from a closed position, the locking component (6), sliding against the door case (2) along its length, finally leaves the case and freely adopts the aforementioned relative angular position. When the door is closed again, the free end of the locking component (6) will come up against the case (2), thus preventing the door from being fully closed.

Description: Arrangement for a door The present invention reLates to an arrangement for a door intended, in conjunction with the cLosing of same, to prevent injury by crush¬ ing between the door Leaf and the case, comprising a body component with a pLane surface intended to be mounted against the door Leaf, in which body component a LongitudinaL Locking component is pivotaLLy mounted. A Large number of such injuries by crushing occurs every year, mainLy to the hands and fingers in conjunction with pLaying with doors or as a resuLt of doors bLowing shut in cross-draughts, etc. Not only are injuries by crushing extremely painful, but they can also cause disfigurement for Life. The object of the present inviention is to make available an arrange- ment which automatically eliminates injury by crushing around all the edges of the door, the manner in which this is achieved being charac¬ terized in that the aforementioned body and Locking components have means which define a relative angular position essentially involving the direction of longitudinal extension of the locking component forming a normal to the plane surface of the body component, which angular position the components are forced to adopt by a spring acting between said body, and locking components in conjunction with which the body component with the locking component mounted in it is intended to be mounted on the inside of the door leaf in a position such that, as the door is opened from a closed position, the locking component, sliding against the door case along its length, finally Leaves the case and freely adopts the aforementioned relative angular position in which, when the door is closed again, the free end of the Locking component will come up against the case and will thus prevent the door from being fully closed. In accordance with one particular characteristic feature of the invention, the arrangement comprises a buffer element intended to be applied to the door case at a point at which the free end of the locking component is expected to come up against the case, which buffer element exhibits a concave, curved contact surface for the aforementioned free end of the Locking component, whereby relatively gentle arresting of the movement of the door towards its closed position is achieved on the one hand, and on the other hand no impact marks are produced on the door case when the free end of the Locking components makes contact with the case. In accordance with a second particular characterist c feature of the invention, the arrangement comprises a snap-action device acting between the aforementioned components and so arranged, against the action of the spring, as to retain the Locking component in a detach¬ able fashion, preferably so that the direction of longitudinal exten¬ sion of the locking components is approximately parallell with the plane surface of the body component. With the help of this snap- action device it is possible, for example, for grandparents to set the arrangement to function only when the grandchildren are visiting. The invention is described below in more detail with reference to the accompanying drawing, which illustrates in plan view from above the function of an arrangement in accordance with the invention during the following phases: door closed. Fig. 1; door prevented from being closed, Fig 2; and arrangement in the inactive position, Fig. 3. The designation 1 is used in the drawing generally in respect of an arrangement in accordance with the invention, which is referred to below as an anti-crushing guard, and the designation 2 is used in respect of a door case with a hinge 3, which supports a door Leaf 4. The anti-crushing guard 1 comprises a body component 5 and a Longi¬ tudinal Locking component 6 pivotally mounted therein. The body component 5 has a plane surface 7 intended to be mounted on the door leaf 4. The mounting of the Locking component 6 in the body component 5 is constituted by a pin 8. The body and Locking components 5 and 6 are executed with devices 5a and 6a so arranged as to define a relative angular position between the components 5 and 6. The aforementioned devices consist, in the embodiment illustrated in the drawing, of two surfaces, which, in the aforementioned relative position, which essentially means that the longitudinal extent of the locking components 6 forms a normal to the plane surface 7 of the body component 5, are constituted by a surface 5a parallel with the plane surface 7 and the end surface 6a of the locking component 6 situated closest to the mounting. The components 5, 6 are caused by a spring 9 arranged in conjunction with the mounting between the body and locking components to adopt the afore¬ mentioned relative position in which the end surface 6a of the locking component 6 rests against the surface 5a of the body component 5. The arrangement 1 is intended to be installed with the plane surface 7 facing towards the inside of the door leaf 4, at a height above the floor such that it is out of reach of small children and in a position relative to the front edge 10 of the door Leaf 4 such that, as the door is opened, the Locking component 6 will first slide along the door case 2 along its length. Once it finally moves out of contact with the case 2, the locking component 6 is caused by the spring 9 to adjust to a position in which it is approxi ately per¬ pendicular to the door leaf 4. When the door is closed once more, the free end 11 of the Locking component 6 will come into contact with the case 2 and will thus prevent the door from being fully closed. The risk of injury by crushing is eliminated entirely in this way, not only between the case 2 and the front edge 10 of the door leaf 4, but also between the case 2 and the edge 12 of the door Leaf 4 facing towards the hinge 3. In order to prevent damage to the case 2 at the point at which the free end of the Locking component 6 is expected to come into contact with the case 2, a buffer element 13 with a concave, curved contact surface 14 for the free end 11 of the Locking component 6 is fitted at that point; see in particular Fig. 2. The concave, curved surface 14 serves the purpose of rendering the braking of the door more gentle. By means of a snap-action device acting between the body and Locking components 5, 6, which device is preferably arranged in the mounting between the aforementioned components, the Locking component 6 is retained against the effect of the spring 9 in an inactive position (see Fig. 3) in which the direction of Longitudinal "extension of the Locking component 6 is approximately parallel with the door Leaf 4. If necessary, the Locking component 6 can be released so as to act in the manner described above.
