Abstract

The present invention relates to a clasp for the connecting of two parts comprising a first (1) and a second (2) clasp part consisting of, against the first part (1) fixed, and from this extending part (3), in the second part (2) an opening (3) the shape of which closely connects to the outer shape of the extending part (3) so that the second part (2) can pass over the latter as well as the means, to restrain the second part on the extending part (3), in the spring-loaded means (8, 10, 11) and an edge or groove (5) arranged inside the second part's opening. The clasp consists of spring-loaded means (6, 7) designed to move the parts away from each other upon the parts being released. A button (4) arranged in the cylinder is placed for activation when the clasp's parts are to be released from each other.

Description

Clasp.
The present invention concerns a clasp for the connecting together of at least two parts, for example, the belts of a harness.
The clasp of the type to which the invention refers can be utilised for detachable connections of belts, bands and other parts in many different contexts. In various forms of execution the clasp can permit greater or smaller movement on the part of the connected parts and may thereby be suited to the requirements that can exist in the various applications.
The object of the present invention is to indicate an improved clasp that can be secured and loosened with one hand. It is also an object of the invention to indicate a clasp, the release mechanism of which requires actuation at only one place.
A clasp in accordance with the invention comprises two parts, a first part with a securing and release mechanism as well as a second part that comprises the means for co- ordination with the mechanism in the first part. This means is comprised in the first instance of arrangements in which one or more parts of the mechanism's moveable parts can intervene. The co-ordination medium preferably also comprises arrangements for facilitating the separation of the two parts when they are released from each other.
An arrangement in accordance with invention and the forms of execution of this possess the characterising properties as shown by the patent claims.
The invention shall be described in detail below in connection with the example of a preferred embodiment as shown in attached drawings.
Figure 1 shows a clasp in accordance with the invention.
Figure 2 shows the clasp viewed from above.
Figure 3 shows the clasp viewed from the side. Figure 4 shows the clasp's first part viewed from the side.
Figure 5 shows a part that is included in the clasp's mechanism.
Figure 6 shows the clasp's first part as a cross-section.
Figure 7 shows the clasp's second part as a cross-section.
Figure 8 shows the clasp's first and second parts as cross-sections without the pushbutton.
The clasp consists of a first part 1 with a mechanism for retaining and releasing of a second clasp part 2. Shown in the figures is the first part as a plate which can be attached to the desired underlay. The first part and/or the second part may also constitute an integrated part of a larger piece as will be exemplified in greater detail in the following. The first part 1 consists of a central part 3 that, in the preferred execution shown in the drawings, is a circular cylinder that is at right angles to the first part. The cylinder is tubular and is bordered upwards by the surface of a push-button 4. The second part of the clasp is shown in the figures as a plate 2 with a circular hole 13, the diameter of which is somewhat greater than the diameter of the cylinder 3. The circular hole 13 has an interior groove 5 which is bordered by an upper edge 14 and a lower edge 15.
The mechanism consists of a spring-loaded locking device 8 which is positioned inside the cylinder and rests on the latter's bottom or in connection to this arranged medium. The locking device consists of a ring-shaped or similar spring as well as two tongues 9, 10 with bevelled outer edges 11, 12. The tongues are telescopically arranged in openings in the cylinder's casing surface. Beneath the tongues there are also two other spring-loaded tongues 6, 7 arranged.
When the second clasp part 2 is introduced over the cylinder and pressed down over the cylinder towards plate 1 , the locking device's tongues 9, 10 are pressed under spring action in towards the centre and permit the clasp part 2 to pass downwards towards the spring-loaded tongues 6, 7 in the first part 1. These tongues are pressed somewhat downwards so that the spring-loaded parts 9, 10 can squeeze into the groove 5 and hold the other clasp part 2 in a determined position in relation to the cylinder 3. Through the cylinder being circular, the second part 2 can rotate freely on the cylinder in this position. Securing and releasing can then take place in an arbitrary position.
The push-button 4 consists of downwards directed rods 16, 17 with somewhat bevelled edges. The rods, which are preferable four in number and in parallel pairs, lie towards the contact surfaces 18, 19, 20, 21 in the spring-loaded ring 8. When the button 4 is pressed downwards the spring is pressed together and the spring-loaded part's tongues 9, 10 are pulled back so that the second clasp part 2 is released from the first clasp part 1. The spring-loaded tongues 6, 7 in the first part press the second part 2 somewhat upward so that, when the pressure on the button 4 ceases, the tongues 9, 10 cannot again squeeze into the groove 5 and the two clasp parts remain free from each other.
The push-button 4 is kept in position through snap arrangements that telescopically grip into the cylindrical part 2. These arrangements do not form part of the invention and are not shown in the figures. Button 4 is controlled, apart from the cylinder's walls, by a centrally positioned downwards directed pin that runs in a corresponding tube.
Over and above what is described above, different forms of execution are possible for the invention concept. The central cylinder, which is described above as being circular, and the corresponding hole in the second clasp part may have some other shape that is suitable for a relevant application. The shape may for example be square, rectangular or elliptical, which affords different possibilities of varying the clasps' parts varying positions to four or two respectively, alternatively without affording it the possibility of free rotation around the cylinder as that provided by the circular shape. There are also other shapes that permit only one mutual position between the parts upon connection. An arrangement in accordance with the invention may also be used for connecting together more than two parts. This appropriately occurs with a part executed like the first part described above as well as two or more "other parts", which can have individual securing arrangements of the nature described above, alternatively only the outermost positioned of these "other parts", have such a securing arrangement. The spring-loaded function in the locking device's tongues may be achieved by means of differently shaped springs. The clasp may, according to the invention, be employed for many different purposes, for example for belts in harnesses, rucksacks and the like, for securing of belts and bands in vehicles, toys and pushchairs as well as in clothes and equipment for sport and leisure. The clasp's one or both parts may thereupon constitute integrated parts of the pieces in which they are employed. In all these applications the clasp's property is that of being able to be manoeuvred simply by means of one hand to advantage.
