VENETIAN BLIND CHANNEL GUIDE FIXTURE Filed Oct. 12, 1952 Patented Nov. 7, 1933 Q UNITED STATES PATENT OFFICE VENETIAN BLIND CHANNEL GUIDE FIXTURE Jesse E. Cooper, Los Angeles, Calii.'., minor to Western Venetian Blind 00., Los Angeles, Calif., a corporation of Delaware Application October 12, 1932. Serial No. 637,456

7 Claims. (01. 156-17) My invention relates to the combination of a pins 27. Each pin has a beveled head 28. The channel guide and a swiveling pin on the end of pin is of such a diameter that it may move freely venetian blind slats to guide the slats in their in the slot between the edging strips, and the vertical movement in the channel, also to allow head is of such a diameter that it will not pull tilting of the slats and to accommodate a slight outwardly through this slot. The pin is secured 60 inclination of the slats in regard to the horizontal. to a plate 29, which plate is attached by screws 30 An object and feature of my invention as reto each slat 20. gards the channel guide is forming this of a hol- In the operation of the channel guide fixture in low structure with a longitudinal slot with two installing the blind in a window, the swivel pins edges forming the opposite sides of the slot and are inserted through the end of the guide. It will 55 t s d s avin a ru r v rin Th s be noted on reference to Fig. 1 that these swivel forms a channel guide, and another feature of in ar on ab t every third, slat, this being found, my inve t on s p ovid a certain number sufficient.

In a venetian blind construction, a structure cord 21 operating through cross slots 22 in each having a longitudinal slot at the side 0! an openslat, and the slats being guided by webbing strips ing, a slat having a pin extendinglongitudinally of 50 23. The slats may also be inclined in the usual the slat, the pin extending through said slot and manner, this being illustrated by an inclining dehaving an enlarged head to prevent removal from vice 24 operated by the cords 25 which incline the the slot in the axial direction of the slat, said upper bar 26 and, hence, all of the slats in the slat being adapted to rotate on the axis of a pin, same direction. and the head preventing removal of the pin and 55 A number of the slats are provided with swivel slat in a longitudinal direction 01 such slat, the

edges of the slot having an edging of resilient material, said material engaging saidpin.

2. A venetian blind construction having a hollow channel structure adapted for locating in'the vertical side 01' an opening, said channel structure having inturned marginal strips with a vertical slot between the strips, a slat having a pin secured thereto extending in an axial direction through the slot, said pin having an enlarged head, the head preventing removal of the pin through the slot in an axial direction of the slat, the strips at the slat. having edgings formed of resilient material, said edgings having a narrow groove fitted on the edge of the strips.

3. A venetian blind construction having a guide channel structure formed of hollow channelshaped metal with inturned strips, and a vertical slot between said strips, the strips at the slot having an edging member of resilient material, a slat having a pin secured to its end and extending in an axial direction, said pin fitting in the slot between the edging members and having a head of larger diameter than the space between said members whereby the slat and pin may rotate on its axis but prevent it from longitudinal displacement in the direction of the axis of the slat.

4. A venetian blind construction as claimed in claim 3, said resilient edging material being adapted to engage the end of the slat on which the pin is mounted and form a sound deadening device.

5. A venetian blind having a hollow channel structure adapted for locating on the vertical side of an opening, said channel structure having a vertical slot, said channel structure and slot being open at the top, a slat having a pin secured thereto at one end, the pin being in axial alignment with the slot and having a circular head of larger diameter than the pin, said head and pin being insertable through the upper open end of the slot, the pin having a clearance on opposite sides of the slot, and the pin having a clearance from the base of the channel structure whereby when the slot is either inclined or tilted said head cannot be withdrawn from the slot.

6. A venetian blind as claimed in claim 5, the channel structure at the slot having edgings of resilient material, said resilient material forming a sound deadening material to engage the pin and to engage the end of the slat should the slat move longitudinally.

7. A venetian blind construction having a guide channel structure formed of hollow channelshaped metal with inturned strips and a vertical slot between said strips, the strips at the slot having an edging member of resilient'material, the slot and channel being open at the top, the slat having a pin secured to its end and extending in an axial direction, said pin having a circular head of larger diameter than the pin, the pin and the head being insertible in the slot and the channel through the top, there being a clearance between the pin and the edging members and the head and said edging members and the base of the channel whereby on longitudinal tilting or rotation of the slat said head cannot be withdrawn from the slot.
