Description

Utility model

The innovation concerns a pair of pliers for connecting horizontally pluggable Parts, in particular flooring panels, which on at least one side have exnen cones and minaesietia ciae-i. <= ΰ '* £ δΓ € ϊϊ apply have a pin receptacle and also vertical recesses.

In the construction of sports facilities, in particular tennis courts, plastic flooring panels are being used to an ever increasing extent. A plate designed as a rectangle or square and provided with vertical water passage openings has become known, which as connecting parts on two adjacent sides in the middle each have a pin and on the other two Each side has a pin receptacle in the center, the flange-like extending downward from the side edge of the plate Approaches are arranged; the over the plate side

Pins protruding from the edge have a longitudinal axis parallel to the plane of the plate and are widened in cross-section at their free end provided, while the pin receptacles a Have an opening with an all-round closed circumference, the cross-section of which is slightly smaller than the cross-sectional enlargement at the end the spigot is.

ff These panels are connected by shifting horizontally. The pin penetrates into the corresponding receptacle of the opposite plate with elastic expansion a, in which it then, when its end cross-sectional enlargement has penetrated the receptacle and this out of it elastic has returned tensioned to its elastically relaxed (starting) position, is locked. In order to achieve a permanent and secure connection of the plates, the dimensions of the connecting parts are chosen so that a tighter as possible Seat is guaranteed; this in turn requires the manufacture

%> len the connection a considerable effort. A further complicating factor is that when several rows of panels are already connected to each other, the horizontal thrust exerted when adding new panels is only partially effective in the desired sense, since a not inconsiderable part is used for elastic I deforming work of the already existing panel rows, because this at the beginning of the connection process, first give in to the direction of force

The hiring is based on the task of connecting such To facilitate flooring slabs and to use the full force used to establish the connection. The solution to this problem is based on the idea of using pliers to make the connection according to the invention characterized in that the one gripper of the pliers as a holder or fixation of the pin receptacle of the one Cover plate and the other gripper of the pliers is designed as a slide for the pin of the opposite cover plate.

Due to the use of pliers, the force required to connect can be kept much lower than E.g. when attaching by hand, with the newly connected plate in the coupling position with mere ping force is pressed; In addition, the use of pliers creates the prerequisite for mechanization of the connection process $ because it can also be operated pneumatically, hydraulically or electrically. The particular design of the pliers is limited the joining process on the two panels to be joined together; a transfer of forces to such Disks that are not involved in the connection that is currently taking place do not take place.

In a further embodiment of the innovation, it is the bracket or fixation of the pin receptacle forming gripper is designed in the manner of a three-pronged fork, the middle prongs of which are shorter than the two outer prongs are, with the lateral distance

the fork prongs is dimensioned such that they are divided into three of each other independent edge-side vertical grooves of the decking platform are pluggable; The cross section of the fork prongs is appropriately slightly smaller than the cross section of the vertical recesses. The two long outer prongs ensure that the pin receptacle is fixed over almost the entire height of the Plate, while the shorter design of the middle prong allows unhindered passage of the pin during manufacture the connection guaranteed. The pluggability in three of each other independent edge-side vertical recesses increases the pressure-absorbing surface and thus has a noticeably elastic effect Change of shape of the entire plate counteracts, while the almost complete filling of the vertical recesses by the fork prongs ensures proper insertion of the pin in front of the corresponding pin receptacle of the adjacent plate.

According to a further advantageous feature of the innovation, the gripper forming the slide for the pin consists of a single, fork prongs extending as an extension of the pliers leg, which is located in the vertical recess located behind the pin reaches below the level of the pin. Here, too, the length of the tine again ensures gripping of the tenon area over almost its entire height.

For certain applications, it can be advantageous if the holder or fixation and the slide with the respective Legs are integrally formed.

In the drawing, a "preferred embodiment" is the Innovation presented.

Show it

Fig. 1 is a view of the pliers according to the innovation in the open position with grippers pushed into the flooring panels that are still undone,

2 shows a partial view of the pliers according to the invention in the closed position with the floor covering panels already connected inserted grippers and

Pig. 3a and 3b the two grippers of the pliers according to the innovation.

In Fig. 1, the complete pair of pliers Z is shown, which has two legs S ₁ and Sp connected to one another in an articulated manner at D. The legs S ₁ and S ₂ are acted upon by a spring F xj expansion direction, ie in the direction of the open position of the pliers Z, a _{chain K arranged at the rear end of the legs S 1} and S ₂ limiting the expansion movement. A gripper G ₁ or G _{2 is} attached to the front end of the legs S ₁ and S _2. In the embodiment shown, the grippers G ₁ and G _{2 form} an independent component fastened to the relevant leg S ₁ and S ₂ by means of retaining screws H ₁ and H _2; however, they can also be in one piece _{with the legs S 1} and S _2.

The Pig. 3a and 3b illustrate the design of grippers G ₁ and G _{2 - The gripper G 1} on the left in Mg. 1 and 2 is designed in the manner of a three-pronged fork, the middle prong M of which is shorter than the two outer prongs A ₁ and A ₂ . In contrast, the one in Pig. 1 and 2 right gripper G ₂ only a single fork prong extending as an extension of the leg S _2.

In Pig. 1 and 2 two facing plates to be connected or connected to one another by means of the pliers Z are indicated, with a pin being provided as connecting parts on the plate on the right in the drawing and a corresponding pin receptacle on the left plate exactly opposite. The grippers G ₁ and G ₂ are pushed into the edge-side vertical recesses of the facing plates in such a way that the gripper G _{2 is} located exactly behind the pin, its length being dimensioned so that it is much deeper than the prongs A ₁ and A _{2 of} the gripper G. ₁ extends into the covering plate, namely below the level of the pin, while the prongs A ₁ and A _{2 of} the gripper G ₁ against the side next to the pin recess and the prongs M against the edge area above the pin recess. If the pliers Z is moved into the closed position, the gripper G ₁ acts as a holder or fixation of the pin receptacle, while the gripper G ₂ presses the pin into it; while the middle prong M of the support gripper G ₁ allows the pin to pass under it due to its shorter design.

The operation of the pliers Z can be done by hand, expediently however, it is operated pneumatically, hydraulically or electrically, especially when larger areas are to be created.
