VENETIAN BLIND George R. Lind, St. Joseph, Mich.
Application February 23, 1951, Serial No. 212,397
10 Claims.
This invention relates to improvements in Venetian blinds.
` The main objects of this invention are:
First, to provide a Venetian blind bottom bar which may be quickly and easily connected to the suspending tapes of the ladder.
Second, to provide a structure having these advantages which may be economically produced and at the same time is attractive in appearance and permits the disconnection of the bottom bar from the ladder tapes for laundering or cleaning or renewal of the tapes.
Objects relating to details and economies of the invention will appear from the description to follow. The invention is pointed out in the claims.
A preferred embodiment of the invention is illustrated in the accompanying drawing, in which:
Fig. 1 is a fragmentary perspective view of a Venetian blind embodying my invention.
Fig. 2 is an enlarged fragmentary view in section on a line corresponding to line 2-2 of Fig. 4.
Fig. 3 is a fragmentary perspective View with the top bar member omitted.
Fig. 4 is an enlarged transverse section on a line corresponding to line 4-4 of Fig. 2.
Fig. 5 is an enlarged fragmentary plan view, with the top member omitted, further illustrating the relation of certain of the parts, a fragment of a'ladder tape being shown in section.
Fig. 6 is a perspective view of the clamp vmember.
In the accompanying drawing, I represents the slats of a Venetian blind and 2 2 the suspending tapes which are provided with slat supporting cross straps, not illustrated. These tapes 2-2 are preferably connected at their lower ends to provide a loop 3. The bottom bar of my invention designated generally by the numeral 4 comprises the bottom member 5 of curved upwardly facing channel section and having inturned anges 6 on its edges. The flanges 6 have slots 1 therein adapted to receive the tapes 2, the end edges of the slots being notched or conformed to provide keepers 8.
The tape clamp member 9 is formed as a sheet metal stamping and has downwardly offset upwardly facing U-shaped springable arms I on its side edges. The outer portions II of these arms are adapted to spring or snap under the keepersv 8. These arms are of such width that when the clamp member is disposed within the loop of the suspending tapes as shown in the drawing and the arms springably engaged with the keepers, the
tapes are clamped against the inner side ofi-thel bottom member 5. Howeven-if for any reason there is not effective clamping engagement be# tween the bottom member and the arms as is 5 indicated in the drawings, the tapes cannot Vbe withdrawn where the lower ends are connected to form the loop 3. ber is in the embodiment illustrated extended to provide a finger piece I2 which facilitates the r`e 10 leasing of the clamp. Y
The arms of the clamp areA provided-With in'" turned lugs I3 adapted to receive and'retaini'n'gly engage the top member I4 which is inthe emv F bodiment illustrated of downwardly facing curved [email protected] and may be sprung to engage with the-f lugs and is retained in engagement therewith byv its inherent springability.
The clamp member 9 is provided with a 'key-v hole slot I5 adapted to receive the suspending; cord I5, the cord I6 being provided with'aknot Il whi-ch may be passed through the enlarged part of the slot I5 and slipped under the Arestricted part of the slot. The top member I4 is provided with a cord receiving slot I8 which is aligned with.
urge them more securely to engaged position, the` flange engaging portion of the 'arms being inclined outwardly as shown in Fig. 4.
the bottom bar maybe quickly released' should occasion require as for cleaning or renewal of 40 the tapes. l I have illustrated my invention in a, highly practical commercial embodiment thereof. I have not attempted to illustrate or describey certain embodiments or adaptations which I contemplate as it is believed that this disclosure will enable those skilled in the art to embody or adapt'- my invention as may be desired.
