BRIEF SUMMARY
CROSS REFERENCE TO RELATED APPLICATION
This application is a national phase application corresponding to PCT/CH 84/00195 filed Dec. 13, 1984 and based upon a Swiss National application 6682/83-9 filed Dec. 15, 1983 under the International Convention.
FIELD OF THE INVENTION
The invention relates to a container, especially for a conveyor system, which comprises a container body closable by a lid, the lid being connected to the container body on one side of the container by a hinge and on the opposite side by means of a snap lock.
BACKGROUND OF THE INVENTION
Containers, particularly for a conveyor system as mentioned above, are known, e.g. from CH-PS 496 603. Because the lid of such a conveyor can be opened only from one side, the access from the other side is very difficult. Moreover, the containers can then be used only in a certain assembly configuration.
OBJECT OF THE INVENTION
It is the object of the invention to provide a container of the aforedescribed type in which access to the interior is afforded from opposite sides of the container.
SUMMARY OF THE INVENTION
This object is achieved with a container which has on each side at least one combination snap closure formed as a hinge, which includes on one section of the container a latch formed as part of the hinge and held in closed position by a spring which cooperates manually detachably with the other hinge portion on the other container section, where the latch and/or the other hinge portion has a ramp surface for the automatic engagement of the combination snap lock. Unobstructed accessibility of the container from opposite sides is assured by the fact that the lock is designed as a combination snap lock which acts both as a hinge and as an opener for the container. Additionally, the automatic engagement of the combination snap lock always assures a secure closing of the container. Moreover, the position of the container in the conveyor system is no longer of importance.
Advantageous features of the container include that the latch is disposed on a lid or that the latch is disposed on the is disposed on the container body. Each latch can be used as a rocker which being on a rocker portion, a nose which in its closed position engages a fixed bearing element for a hinge pin disposed in the other container section.
Each latch is designed as a hinge pin axially slidable in a guide and which, in its closed position, engages the bore of a bearing element. claims 2-5.
BRIEF DESCRIPTION OF THE DRAWING
The invention is described in detail below in accordance with the drawing which shows:
FIG. 1 a container with combination snap locks arranged on opposite sides in vertical section and in part;
FIG. 2 a combination snap lock on one side of the container in perspective view; and
FIG. 3 another combination snap lock in partial vertical section along the linkage axis.
SPECIFIC DESCRIPTION
FIG. 1 shows a container which may be used for a conveyor system according to CH-PS 496-603. This container comprises a container body 2 which is closed by a lid 4. Combination snap locks 8 are arranged on the longitudinal sides 6 of the container which may be used for either for opening the container or as hinges.
Each combination snap lock 8 has two block-shaped bearing elements 10 mounted on a side wall 12 of the container body 2. On these bearing elements 10, a latch 14 is rotatably journaled and is realized as a plate-shaped rocker 26. An upper rocker portion 18 contains noses 20 which engage the fixed bearing element 10 in the closed position shown. Each bearing element 10 contains on the side 22, which is engaged by the nose 20 of latch 14, a recess 24 for accepting a hinge pin 26 connected to cover 4 by means of a band element 28. The hinge pin 26 is held in the bearing recess 24 by means of nose 20 which protrudes over side 22 of the bearing element 10. A spring 30 is used for pretensioning the latch 14 into the closed position shown. The latch 14 has on its upper side a ramp surface 32 which enables the automatic actuation of the combination snap loc
