Definitions

  • the present invention relates to a device at signs, whereby each sign has display members which include an elongate carrier rod of preferably a great length and which carrier rod is vertically oriented and provided to rotate about a longitudinal shaft, whereby first blades on a series of display members mounted beside each other are adapted to together define a first image, whereby second blades on said series of display members located beside each other are adapted to together define a second image, whereby preferably at least third blades on said series of display members mounted beside each other are adapted to together define at least a third image, whereby said first image can shift to said second image and preferably to at least one third image by rotating the display members and whereby the carrier rod is provided with retaining means through which the blades are mounted on said carrier rod.
  • the display members are often long - normally 2 m or more. This means that one does not reach up to the upper retaining means of the carrier rods when a new blade is to be snapped in position thereon and it has been necessary to hit the upper portions of the blade with a club or similar with a long hand grip in order to have the blade to snap in position at the top.
  • the object of the present invention has been to eliminate this problem by means of a simple and suitable device, which is defined substantially by the characterizing features of subsequent claim 1.
  • the device according to the invention permits that one from below can bring the blades into engagement with upper retaining means instead of snapping the blades thereinto, which means that the blades are quickly mounted at the top without tools and far above one's own reach.
  • the sign illustrated in fig. 1 includes a frame 1 with a series of display members 2 which are located beside each other and oriented vertically.
  • Each such display member 2 preferably has a great length - e.g. 2 m or more - and it comprises a longitudinal carrier rod 3 which is adapted through retaining means 4, 5 to carry three blades 6 in such manner that the display member 2 gets a trilateral or triangular cross section.
  • Each carrier rod 3 is down below and at the top journalled on the frame 1 and cooperates with a pivoting device (not shown) which can pivot or rotate the carrier rod about a longitudinal shaft such that first one of the blades is turned or facing forward, then a second blade 6 and thereafter a third blade 6.
  • the sign can first show an image which a first blade 6 at all display members 2 located beside each other define together, whereafter the sign can change the first image to a second image which a second blade 6 of all display members 2 define together and finally, change the second image to a third image which a third blade 6 of all display members 2 define together.
  • Each carrier rod 3 preferably comprises an elongate hollow profile having three longitudinal retaining portions 7 and retaining means 4, 5 for a blade 6 is provided on each retaining portion.
  • the retaining means 4, 5 are preferably provided with two inner retaining shanks 8, 9 for being threaded onto the longitudinal retaining portions 7 of the carrier rod 3.
  • the inner retaining shanks 8, 9 are preferably elastic so that the retaining means 4, 5 also can be snapped into the retaining portions 7, if desired.
  • the retaining means 4, 5 preferably have the same cross-sectional shape so that they can be manufactured with the same moulding tool.
  • the upper retaining means 4 is preferably considerably longer than the lower retaining means 5.
  • the retaining means 4, 5 have two outer retaining shanks 10, 11 which together with the inner retaining shanks 8, 9, define two female shaped retaining portions 12, 13 in which two male shaped retaining portions 14, 15 on the blade 6 can be fixed in such a way that said male shaped retaining portions 14, 15 are stuck in said female shaped retaining portions 12, 13.
  • the female shaped retaining portions 12, 13 of the upper retaining means 4 preferably have entrances 16, 17 which are designed and/or located such that the male shaped retaining portions 14, 15 of the blade 6 can be fixed by insertion thereof from below into said entrances 16, 17 also if the blade is held in a somewhat inclined position L (see figs. 1, 3 and 4) relative to the carrier rod 3 when the blade 6 is moved in a direction U upwards towards the upper retaining means 4.
  • the upper retaining means 4 also includes a preferably downwardly directed end portion 18 which is designed to facilitate insertion of the male shaped retaining portions 14, 15 of the blade 6 into the retaining portions 12, 13 of the upper retaining means 4.
  • This end portion 18 can preferably have two tongues 19 and 20, each of which defines an extension downwards of such inner sides of the retaining portions 12, 13 which are defined by the inner retaining shanks 8, 9.
  • Each such tongue 19, 20 diminishes in thickness in downward direction and each tongue 19, 20 engages side surfaces 7a and 7b on the retaining portion 7 of the carrier rod 3.
  • the downwardly directed end portion 18 is also designed to permit that those central parts 21 of the blade 6 that are provided between the retaining portions 14, 15 of the blade 6 easily can slide up onto the upper retaining means 4.
  • the end portion 18 preferably has a central tongue 22 which defines an extension downwards of a central member or part 23 of the upper retaining means 4.
  • the thickness of the central tongue 22 diminish successively in downward direction and said tongue engages a central surface 7c on the retaining portion 7 of the carrier rod 3.
  • the blade 6 can down below be fixed to the retaining means 5 such that it can not slide downwards and out of engagement with the upper retaining means 4.
  • the blade 6 can preferably be snapped into the lower retaining means 5 by pressing the lower portion of the blade 6 in radial direction R (see fig. 4) towards the carrier rod 3. Since the outer retaining shanks 10, 11 of the lower retaining means 5 are elastic, said shanks can be pressed aside by means of the retaining portions 14, 15 of the blade 6 and when they later are in engagement with the female shaped retaining portions 12, 13 of the lower retaining means 5, the elastic retaining shanks 10, 11 can spring back for retaining the blade 6 down below.
  • the retaining portions 14, 15 of the blade 6 may be elastic instead of those of the lower retaining means 5 or may the retaining portions of both the blade 6 and the lower retaining means 5 be elastic.
  • retaining means 4 can be advantageous to provide more than one upper retaining means 4, preferably two, beneath each other at the top of the carrier rod 3 in order to insert the retaining portions 14, 15 of the blade 6 from below into more than one retaining means 4 and thereby increase the retaining grip on the blade 6 at the top.
  • These retaining means 4 are preferably of identical design, but they can alternatively have different shape.
  • the carrier rod 3 can be provided with more than one retaining means 5 beneath the upper retaining means 4 and the blade 6 can be snapped in position on all these additional retaining means 5 beneath the upper retaining means 5. All the retaining means 5 located beneath the upper retaining means 4 preferably have identical shape.
  • the upper retaining means 4 is preferably fixed at the carrier rod 3 such that said means can not be displaced when the retaining portions 14, 15 of the blade 6 are brought in engagement therewith.
  • This fixing is carried out by means of one or more fixing or mounting screws 24, 25.
  • the lower retaining means 5 can also be fixed at the carrier rod 3 e.g. by means of a mounting screw 26.
  • the longitudinal retaining portions 7 of the carrier rod 3 and/or the blade 6 and its retaining portions 14, 15 are preferably designed so that the retaining portions 7 of the carrier rod 3 can be used to guide the blade when it is moved upwards towards the upper retaining means 4 (see fig. 6), whereby the blade retaining portions 14, 15 are more easily brought in engagement with the retaining portions 12, 13 of the upper retaining means 4.
  • the outer retaining shanks 10, 11 of the upper retaining means 4 can be elastic so that the blade 6 can be snapped in position at the top instead of being fixed by movement thereof from below into cooperation with the upper retaining means 4.
  • the upper retaining means 4 can be utilized for either insertion or snap-in action of the blade retaining portions 14, 15.
  • the invention is not limited to the embodiment described above and shown in the drawings, but may vary within the scope of the following claims.
  • the display members 2 instead of three blades have two, four, five or more blades.
  • the carrier rod 3 can be designed otherwise and so can also the retaining means 4, 5, which instead of having the same cross-sectional shape can have different cross-sectional shapes.
  • the lower retaining means 5 can be designed to permit another fixing of the blade 6 than by a snap-in action and/or said means can be integral with the carrier rod.
  • the retaining means 4, 5 and blades 6 can have another number of retaining portions than two.
  • the blade 6 can have another shape than described and shown.
