Definitions

  • the invention relates to the frames of bicycles, and in particular, though non-exclusively, to the frames of bicycles equipped with an auxiliary engine mounted on the front fork.
  • Such a saddle support member is very advantageous owing to the simplicity of its construction and its easy cleaning.
  • the saddle support member is usually made of a relatively thick iron-sheet owing to the many functions it has to perform, and since it withstands alone most of the efforts the frame is subjected to through the crank-gear. Thus such a frame is quite heavy due to the relatively important size of said saddle support member.
  • the object of the invention is to provide a frame assembly much lighter than the former and having the required sturdiness to perform the above mentioned functions.
  • Another object of the invention is to provide for a better distribution of the efforts the frame is subjected to on the different members or struts constituting said frame.
  • the frame according to the invention comprises a slanted front strut carrying in its upper part a sleeve for journalling the steering elements of the bicycle, a saddle support slanted in a direction inverse of that of said front strut, a substantially horizontal rear fork rigidly secured, on the one hand, by its own extremity to said front strut above the lower extremity thereof and, on the other hand, at the lower extremity of said saddle support, said frame further comprising a rigid sole rigidly secured, by its upper end to both the lower extremity of said saddle support and the horizontal fork and, by its lower end, to the lower extremity of said front strut, whereby said sole, the lower portion of said front strut and the front portion of said horizontal fork define a rigid triangle.
  • the former saddle support member is now constituted of the two distinct elements consisting of the rigid sole and the saddle support above said sole, and, according to another feature of the invention the sole is made of a relatively thick iron sheet enabling the latter to bear the principal efforts generated in the frame whereas the saddle support is made of a relatively thin sheet sufficient to enable said saddle support to accomplish its only role of supporting the user.
  • the frame is adapted, according to a further feature of the invention to carry on a side plate or check a mechanism which may act upon the efiiciency of said brake by controlling the axial position of the extremity of said flexible sheath, on the side of said working element, said mechanism comprising a lever, one arm of which can be readily reached from outside and the other arm of which is applied through the tension of the cable against an abutment integral with said cheek, abutment such as an assembling bolt, the swivel pin of said leverbeing constituted of a bolt passing through an elongated aperture provided in said cheek and screwed into a small plate lapping said abutment without play.
  • FIG. 1 shows a side elevation of a bicycle provided with an auxiliary engine and with a frame according to the invention
  • FIGS. 2 and 3 show respectively, on an enlarged scale, a vertical partial section of a part of said frame and a horizontal section thereof along the line III-III of FIG. 2;
  • FIG. 4 shows on an even larger scale than in FIG. 2 a vertical section, parallelto the same of FIG. 2, of an embodiment of the brake control mechanism according to the invention and carried by said frame.
  • the sole 1 carrying the housing 2 of the crank-gear 24 is made of a relatively thick iron sheet and is rigidly secured, by its lower end, to the lower extremity of the front strut 12 of the frame and is also rigidly secured by its upper end, on the one hand, to the arms of the rear fork 14, whose front extremity is also connected to said front strut, and, on the other hand, to the saddle support 6.
  • the lower part of the front strut 1-2, the front part of the rear fork 14 and the sole itself constitute a rigid approximately equilateral triangle.
  • the sole 1 has the form of a lid for a rectangular box, said sole being made of a thick iron sheet (for instance having a thickness of 2 millimeters) with folded longitudinal and vertical borders or cheeks 1 This sole is strongly slanted downwardly and forwardly with respect to the horizontal direction.
  • the two longitudinal and vertical cheeks 1 are respectively perforated of a first pair of holes 1 facing each other transversely and adapted to receive the housing 2 of the crank-gear, of a second pair of holes 1 facing each other transversely and adapted to receive the pivoting axis 3 of a support stand 4 serving to stabilize the bicycle in a standing position when not in use, said cheeks being further perforated, in their upper part, of a third pair of holes 1 facing each other transversely and adapted to receive a bolt 5.
  • This bolt 5 itself passes through the two lateral checks of the saddle support 6 in the proximity of their lower ends as will be described hereafter.
  • This saddle support is itself constituted by a U-curved iron sheet turning its concavity to the rear and having two cheeks receiving in their lower part said bolt 5 and enveloping, like a fender, in a manner known per se a part of the rear wheel.
  • This sheet may be much thinner than the same of said sole; for instance have a thickness of 1.2 millimeters.
  • the bottom of the lid constituting the sole 1 is provided with a first opening 1 (FIG. 2) for the passage of the brake cables 7 (FIG. 4) and the electric wires'leading to the tail light, and with a second opening 1 bordered with two folded vertical and longitudinal cars 1
  • These two ears 1 are perforated with a pair of holes 1 facing each other and adapted to receive a bolt 8 for securing rigidly on said sole the lower end of the front strut 12.
  • the front strut 8 is constituted by a section iron, the upper portion of which is welded to the steering sleeve 9 3 (FIG. 1) for slidably journalling the front fork and the stem of the handle bar 11.
  • This front strut 12 is preferably a tubular and straight iron section made of a relatively thin iron sheet (for instance having a thickness of 1.2 millimeters) which hasbeen curved to form a hollow tube with two opposite borders which have been brought to face each other or to juxtapose and finally welded together as shown in FIGURE 3.
  • the welded longitudinal band of the front strut 12 so formed is covered by a protection and trimming strip 13 made of a rust-proof steel or different material.
  • the rear fork 14 of the bicycle comprises two arms made of two angle irons which are both secured, on the one hand, by their front extremities to the section iron 12 through a transversalassembling bolt 15 and, on the other hand, to the sole 1 and to the saddle support 6 through the above mentioned bolt 5.
  • the sole 1, the front portion of the angle irons 14 and the lower portion of the front strut 12 define a non-deformable rigid triangle having substantially an equilateral shape.
  • the different parts above described of the frame are very easy to dismantle and to reassemble.
  • a rear luggage carrier 22 is provided.
  • a spring 25 (FIG. 2) for the support stand 4, said spring 25 being stretched between said stand support and a ring 1 formed in the bottom of the sole 1 at the border.
  • a feet-supporting plate 26 for instance made of a between the front strut 12 and the saddle support 6.
  • FIG. 2 shows equally that the front and rear abutments, which limit the pivotal motions of the support stand 4, are respectively constituted by the inferior folded border 1 of the sole 1 (for the standing position of the bicycle when not in use), and the crank-gear housing 2 This mechanism is adapted to act on the axial position of the extremity 27 of the axially undeformable sheath.
  • Said mechanism comprises essentially a bent lever 28, a first arm 28 of which can be easily reached from outside whereas its second arm 28 is biased against an abutment 32 integral with the cheek 1 this abutment being advantageously constituted by the bolt 5 or its guiding tube (FIG. 4).
  • the pivot pin of said lever is a bolt 29, whose head can easily be reached by means of a wrench.
  • This bolt 29, which passes. through the lever 28, also passes through an elongated or oblong aperture 30 provided in the check 1 and oriented in a direction substantially parallel to the cable 7,' said bolt being screwed in a little plate 31 provided with the corresponding threaded hole said' plate lapping the abutment 32 Without play.
  • the cable 7 passes through the lever 28 near the axis of plastic material and covering the two angle-irons 14 r the pivot pin thereof and the sheath 27 of said cable is adapted to have its remotest extremity 27 from the hand grip 33 to come in abutment against said lever 28 thereby biasing the arm 28 thereof against the abutment 32.1
  • crank-gear said rigid .sole being rigidly secured .by its upper end to both the lower extremity ofsaid saddle support and the horizontal fork, and by its lower end to the lower extremity of said front strut, whereby said sole, a portion of said front strut starting from its lower. extremity and a portion of said horizontal fork starting from its'front extremity define a rigid triangle.
  • 2.1A frame for a bicycle comprising a slanted front strut carrying in its upper part a sleeve for journalling the steering parts of the bicycle, a saddle support slanted in a direction opposite to that of said front strut, said front strut and said saddle support being formed of a relatively thin folded .iron sheet sufiicient to support the user of thebicycle, a substantially horizontal rear.
  • the littleplate 31 permits the motion of said bolt 29 within the elongated aperture 30 in response to the said saddle support, said bicycle frame further comprising a rigid sole slanted in the same direction as said saddle support for carrying the housing of the crank-gear, said rigid sole being made of a relatively thick folded iron sheet for enabling said sole to withstand the efforts generated in the frame by the crank-gear, and said rigid sole being rigidly secured by its upper end to both the lower extremity of said saddle support and the horizontal fork.
  • a frame for a bicycle according to claim 2 wherein said sole is provided with folded borders surrounding a flat bottom, two opposite ears being partially cut out from said bottom and folded to come in vertical longitudinal planes, said sole and said front strut being rigidly connected by a bolt passing through said ears.
  • a frame according to claim 2 for a bicycle equipped with a brake whose working element is actuated through a cable sliding within a flexible but axially undeformable sheath, wherein said sole is provided with folded borders defining vertical and longitudinal cheeks, at least one of said cheeks being provided with an elongated aperture, an abutment integral with said one cheek, a plate lapping said abutment and provided with a threaded opening in front of said elongated aperture, a bolt element screwed into said threaded opening and passing through said elongated aperture for locking said plate in position with respect to said one check, a bent lever pivoting about said bolt element and having a first arm biased against said abutment by the tension of said brake cable and a second arm easily reached from outside for shifting sa-id lever in a direction opposite to said biasing for modifying said tension.
