* Support for bicycles or the like. ■

The innovation relates aioh to a support that can be set up For example, a bicycle outdoors, preferably with a one-legged arm that can be pivoted in the direction of travel Support foot is provided and attached to the frame tubes can be.

The task of the fire is to provide the support leg with threads in a simple manner, which serve to accommodate fastening screws.

With previously known supports made of strip sheet metal fitting are made, only a small material thickness is available for the »thread. The shaped sheet metal piece has therefore been reinforced by welded or pressed-in solid pieces in order to increase the material strength required for a thread to have. The attachment of such additional pieces of material requires additional operations and requires an increase of weight.

According to the control are od with a support for bicycles. Like. From strip sheet metal pieces opposite one another.Rändteile of the strip sheet metal pieces parallel to each other at a distance of a screw endurohme it s bent and with threads Mistake. Such a design of the thread is easy relatively easy to manufacture and gives a substantial reinforcement due to the deformation work of the support. at

corresponding width of the strip sheet molding laeeeii see thus oMe © öwichtszunahme also 1 longer .. attach thread » which have sufficient strength.

Preferably, the bent hand parts are designed in cross section perpendicular to the thread longitudinal axis ± 3? Orm of two chin profiles opposite one another with their base lines.

In a special embodiment, the strip sheet metal fitting is used with threads cut into the bent parts of the hinge as a feil one preferably encompassing the frame tubes Clamping device designed * This clamping device consists expediently of a wedge-shaped clamping piece, the a hole for a screw and a contact surface for whose head has and another piece of Kleiam serving as a nut »the also bent part of the band with an extended! Thread and with the appropriate OK in the other clamping piece engages the two clamping stacks are connected by a thread extra cap

The drawing shows an example of the renewal shown »

Sine bicycle ο «dgl» support is essentially composed from a clamping piece a, a clamping piece b> a threaded screw of one that can be swiveled around a t-pivot pin ο, dgl · d Support foot e, as well as a housing f #

The two Kleminstüoken are preferably andt, as can be seen from the drawing, for example , »double wedge-shaped hollow bodies, arranged one above the other and facing the direction of travel, of extreme durability

These clamping pieces © are used to attach the leg support to the 3? Ahr ζ eughint erbau »and, as is well known, in the area the bite frame tubes g and you see immediately behind a saddle seat tube below "are"

As shown in Figure 1 · seen the drawing, bottom "or · overlap while the clamping piece β a and b g and the Drill * wherein tine threaded Very & ube c kev cohesion <ensured h corresponding to both Klemmstüeke.

The upper clamping piece a shows in cross-section an internal profile, the web of which is provided with a long hole-like bore a1 for the passage of the screw thread through and, with incised threads, form a partially open thread that receives the lower part of the threaded screw c. With the screwing on of this threaded screw c, the two clamping pieces a and b press firmly against the frame tubes g and k .

An attachment plate b1 is attached to the lower clamping piece at which the stud foot is el angolen & t by means of the pen and the Movement of the support foot in the direction of travel permitted »whereby additional east elements are provided for the footrest Lock in the position of use or out of use "

33er support foot consists of a rounded shaped sheet metal piece in which the actual pump part is guided so that it can be moved lengthways. Burcli a slot in the outer hinge plate format piece is a screw with the interposition of a washer in the thread of the iFufötfeiles "1" Bntop - like the tightening of the screw, the S ¹ part can be attached higher or deeper in the outer BaMblebb.forBist ^: ieÄ e "

With the stretching of the thread length into the curved sand parts of the eleram pieces or the foot support part, relatively long threads are created which, instead of a nut

The fastening of the drawn-in screws is used to press the edge parts of two generally ripe Klewmetücke against each other, so that a certain wedge effect "creates" which holds the jointly connected parts.

33uroh the new Poraaag of the Baaälbleteile is this A holie strength is given, so that there are two office bends or breaks are largely avoided »If you put the Individual parts aueätalicix made of light metal, bo results a substantial weight saving,

Practice shows that there is an example in a 3 5Bm. strong Material bent over according to the control, G-e? / Inde tone 10mm in length can be incorporated without any additional MATERIAL EXPENSES.
