Abstract

This invention relates to a safety device, and in particular to a safety device for a sliding panel, such as a patio door. The safety device includes an abutment (20), a carrier (21), for the abutment (20), a mounting arm (22) for the carrier (21), a pivot (25) for the mounting arm (22), a support (24) for the pivot (25), resilient bias element (36) urging the mounting arm (22) towards an abutment condition, the resilient bias element (36) being connected between the mounting arm (22) and the support (24), and manually operable member for moving the abutment (20) against said resilient bias (36), the carrier (21) being substantially parallel to the pivot (25).

Claims

1. A safety device which includes an abutment means, carrier means carrying said abutment means, a rigid mounting arm mounting said carrier means, pivot means carrying said mounting arm, said pivot means being substantially parallel to said carrier means, rigid support means supporting said pivot means, resilient bias means urging said mounting arm towards an abutment condition, said resilient bias means being separate from but connected between said rigid mounting arm and said rigid support means, said abutment means being movable manually in one direction to an inoperative position against said resilient bias, retaining means to hold said abutment means in said inoperative position, said retaining means being releasable to permit said rigid mounting arm and said abutment means carried by said mounting arm to be moved in the direction opposed to said one direction by the resilient bias, said support means including a pair of walls, said walls locating said mounting arm therebetween, and wherein said mounting arm includes a pair of planar arm sections, said planar arm sections mounting said carrier means therebetween, and wherein one of said walls defines a recess, a peg within said recess, said peg acting as a retaining member for said mount arm against said resilient bias means.

2. A safety device which includes an abutment means, carrier means carrying said abutment means, a rigid mounting arm mounting said carrier means, pivot means carrying said mounting arm, said pivot means being substantially parallel to said carrier means, rigid support means supporting said pivot means, resilient bias means urging said mounting arm towards an abutment condition, said resilient bias means being separate from but connected between said rigid mounting arm and said rigid support means, said abutment means being movable manually in one direction to an inoperative position against said resilient bias, retaining means to hold said abutment means in said inoperative position, said retaining means being releasable to permit said rigid mounting arm and said abutment means carried by said mounting arm to be moved in the direction opposed to said one direction by the resilient bias wherein said mounting arm comprises a pair of arm sections, and said carrier means includes opposed extensions protruding from said mounting arm sections, said protruding extensions carrying finger grips.

3. A safety device according to claim 2 wherein said carrier means is a pin, wherein said finger grips comprise a pair of removable finger grips mounted one at each end of said pin, said finger grips providing a means to move the abutment manually in said one direction.

4. A safety device which includes an abutment means, carrier means carrying said abutment means, a rigid mounting arm mounting said carrier means, pivot means carrying said mounting arm, said pivot means being substantially parallel to said carrier means, rigid support means supporting said pivot means, resilient bias means urging said mounting arm towards an abutment condition, said resilient bias means being separate from but connected between said rigid mounting arm and said rigid support means, said abutment means being movable manually in one direction to an inoperative position against said resilient bias, retaining means to hold said abutment means in said inoperative position, said retaining means being releasable to permit said rigid mounting arm and said abutment means carried by said mounting arm to be moved in the direction opposed to said one direction by the resilient bias wherein said resilient bias means is a torsion spring, part of said torsion spring surrounding a part of said pivot means.

5. A safety device which includes an abutment means, carrier means carrying said abutment means, a rigid mounting arm mounting said carrier means, pivot means carrying said mounting arm, said pivot means being substantially parallel to said carrier means, rigid support means supporting said pivot means, resilient bias means urging said mounting arm towards an abutment condition, said resilient bias means being separate from but connected between said rigid mounting arm and said rigid support means, said abutment means being movable manually in one direction to an inoperative position against said resilient bias, retaining means to hold said abutment means in said inoperative position, said retaining means being releasable to permit said rigid mounting arm and said abutment means carried by said mounting arm to be moved in the direction opposed to said one direction by the resilient bias, wherein said support means defines a first spring aperture wherein said mounting arm defines a second spring aperture, said first and second apertures receiving respective ends of said resilient bias means, and wherein said aperture in said mounting arm is a closed ended aperture, the open end of said aperture being remote from the aperture in said support means when said mounting arm is in the abutment condition.

6. A safety device which includes an abutment means, carrier means carrying said abutment means, a rigid mounting arm mounting said carrier means, pivot means carrying said mounting arm, said pivot means being substantially parallel to said carrier means, rigid support means supporting said pivot means, resilient bias means urging said mounting arm towards an abutment condition, said resilient bias means being separate from but connected between said rigid mounting arm and said rigid support means, said abutment means being movable manually in one direction to an inoperative position against said resilient bias, retaining means to hold said abutment means in said inoperative position, said retaining means being releasable to permit said rigid mounting arm and said abutment means carried by said mounting arm to be moved in the direction opposed to said one direction by the resilient bias, wherein said support means has a cammed formation engageable by a complementary formation on said mounting arm to limit movement of said mounting arm against said resilient bias means.

7. An assembly comprising a framework, a panel slidably mounted in said framework for engagement of a panel leading edge with a framework closure jamb, and a safety device which includes an abutment means, carrier means carrying said abutment means, a rigid mounting arm mounting said carrier means, pivot means carrying said mounting arm, said pivot means being substantially parallel to said carrier means, rigid support means supporting said pivot means, resilient bias means urging said mounting arm towards an abutment condition, said resilient bias means being separate from but connected between said rigid mounting arm and said rigid support means, said abutment means being movable manually in one direction to an inoperative position against said resilient bias, retaining means to hold said abutment means in said inoperative position, said retaining means being releasable to permit said rigid mounting arm and said abutment means carried by said mounting arm to be moved in the direction opposed to said one direction by the resilient bias, mounted to said framework so that in said abutment condition said abutment means is between said panel leading edge and said framework closure jamb.

8. An assembly comprising:

a. a framework;

b. a panel slidably mounted in said framework, said panel having a leading edge;

c. said framework having a closure jamb engageable by said leading edge of said panel;

d. a safety device mounted upon said framework, said safety device comprising;
