摘要:
A lock device for exhibit framework has a lock shell (1), a lock plate (2) and an eccentric lock wheel (3). On the lock plate (2) there are two long grooves with different width extending to front end of forming there prongs with different width thereof. The front end of every prong is respectively made into claw (21, 22, 23), with opposite directions other. The rear end of lock is curved into the form of U-shaped half loop (26), which is a plane on the end surface (261). The support structure consists of three respective oblique planes (231, 211, 221) of the three prongs and relative oblique bearing surface (131, 131, 111) in the front of the lock shell (1), furthermore, the stop structure consists of a stop dent (27) of the lock plate (2) and an eccentric cam (332) of the eccentric lock wheel (3).

A passage communication member is fitted in a first passage in a structural member, and has a head which is mounted in a slot in another structural member. The first passage in the structural member and a passage in the other structural member are held in communication with each other through a through hole that is defined in the passage communication member. Alternatively, a first engaging member is inserted in a recess defined in a structural member, and a second engaging member is retained in a slot in another structural member. When the first and second engaging members are coupled to each other by a fastening member, the structural members are firmly joined and fixed to each other.

The present invention relates to a closing bushing (7) which is intended for a clamping device (2) used for removably connecting two profiled parts (1). The clamping device (2) comprises an adjustment knob (6) in which a profiled part (1) can be locked and which can be inserted in a recess (5) formed in said profiled part (1). The closing bushing (7) is designed for the form-fitting reception of the clamping device (2) body through a recess (16), and comprises a bore in which the adjustment knob (6) can be received. The surface oriented in the introduction direction (12) of the clamping device (2) in the closing bushing (7) is larger than the corresponding surface of the adjustment knob (6). A clamping device provided with such a closing bushing (7) exhibits a greater resistance to the traction forces applied in the direction of the arrow (12). Clamping devices (2) of the above-mentioned type can also be used for profiled parts (1) made of materials different from the traditional ones, such as wooden parts.

A quick-action connecting device for the detachable connection of wall or frame parts has a locking body manufactured from a U-shaped leaf spring ending in locking noses which can be inserted into openings of a part to be held. The openings are provided with undercut portions, and the locking noses can be fixed in their locking position by means of a rotating body by spreading. The rotating body can press on the springing U-legs of the leaf spring. The quick-action connecting device can be anchored, by means of projections of its rotating body or a bearing journal, in one of two parts to be connected with one another.

The invention concerns a clamping device for detachably connecting two profiled parts (1, 19). There can be inserted and secured in a first profiled part (1) an insert core (2) comprising an axially movable slide (7) with an end part having a projection (17, 18) which can be at least partially inserted into an opening in a second profiled part (19) in order to exert clamping pressure against a portion of the second profiled part (19), which portion partially closes the opening. The slide (7) is flat, and the insert core (2) comprises two inner grooves for axially guiding the slide (7). Rotatably guided in the insert core (2) is an eccentric (5). When the eccentric head (4) is rotated, the eccentric roller (22) presses against the inner wall (30) of a recess (12) in the slide (7) in order to move the latter into the insert core (2) into a position which enables the projection to exert the aforementioned clamping pressure.

摘要:
A locking device for assembling tubular frame components of exhibit framework structures and the like, including an elongated box-like housing sized to be received in a cavity of one of the frame components, the housing having an open coupling end provided with protruding spaced apart coupling ear formations integral with the housing adjacent top and bottom walls thereof and flanking the opening of said coupling end. An elongated thin spring-metal interlocking latching member is movable in the housing by a cam and has a recurved hook formation on one end thereof spanning the space between and aligned with the ear formations. An intermediate bend portion of the latch-member slidably bears against a sidewall of the housing and an integral spring leg extends angularly therefrom in inclined relation to and seated in a slot in an opposite sidewall of the housing for subjecting the bend and leg portions to tensile bending moments flexibly distorting the latching member to displace the hook formation laterally between latching and unlatching relation to an undercut recess in another of the frame components.
摘要:
A lock of the type generally described in Australian Patent Specification No. 552,608, comprising a bearing housing, a holding member and an eccentric pin, generally disposed and mechanically inter-related in the manner described in said specification, the holding member having a slot through which extends the journal of the eccentric pin; characterized in that the slot is so configured as to ensure that inadvertent rotation of the pin beyond the normal locking position is avoided.
摘要:
A fastening device including a housing element, a body rotatable for at least an arc in the housing element, and a resilient element located between the housing element and the body. The resilient element has arms movable between a disengagement position, at which the arms are near one another and extended, and an engagement position, at which the arms are moved away from one another and retracted for a traction engagement with the walls of an engagement hole. The body has cam parts for forcing the arms from the disengagement position to the engagement position, when the body is rotated.
