Definitions
- the jack when the longitudinal recess or groove is provided, the jack can be properly aligned relative to the vehicle on the basis of the direction of the floor pan sill seam weld.
- the insert can be a plastic material to prevent damage to the vehicle being raised. This also means it can be injection molded and if desired, coloured as an aid in use.
- This aspect of the invention can be used with either of the first two aspects discussed above and/or the third aspect mentioned above, namely the freely pivoted base.
- the end of the screw adjacent to the base is received in a support member which simultaneously operated as a pivot to join the base and the corresponding support member.
- This support can be made of a plastic material with a pair of grooves adjacent to each other to admit respectively, the edges of the recesses on the base and the corresponding support member. In the centre, between these pairs of recesses lies a barrel section with a transverse bore in which the end of the threaded part is set.
- the support may be shaped specially to facilitate the initial assembly of the parts followed by the rotation of the support member to prevent subsequent inadvertant disassembly. This is a very simple and convenient way of providing independant movement for the base, the support member and the worm screw with a single item on the apparatus. This can provide reliable contact with the ground and eliminate any undesireable rocking movement.
- a vehicle jack including two support members pivoted together, a base pivoted on a support member and a vehicle engaging section on the other support member so that the base and vehicle engaging section move towards or away from each other a threaded member which is attached rotatably at one end to one of the support members and which passes through a threaded support on the other support member.
- the threaded support is in a barrel or boss extending across the U channel section which comprises the other member mentioned and through slots on the walls thereof, the said slots being shaped to allow initial insertion of the barrel and to prevent any movement thereof once the barrel has been engaged with the threaded member when the jack is assembled.
- This aspect of the invention can be used with one or more of the preceding aspects. This allows the simple insertion of the barrel followed by its movement to the position of operation in which the barrel cannot be removed while it can rotate sufficiently to allow the jack to be raised and lowered.
- the slots in which the barrel is situated are located on the channel section wings of the arm or arms, as the case may be, and are closed off with no outlet towards the edges of the said wings. This is specially advantagous since it completely eliminates any undesireable projection or but as can be appreciated later.
- One last aspect of the invention relates to the positioning of the jack when the worm screw is connected to the barrel in the second support member and to the other barrel or boss in the base or support shoe on the first support member.
- the second member which includes the vehicle engaging support is shorter than the distance between the axle and the point where it engages so that the vertical of the axle and the support are separated a certain distance.
- FIG. 1. is a side view of one elevation of the jack in accordance with the invention.
- FIG. 2. is a perspective of the top part of the jack in FIG. 1. showing the rotatable vehicle engaging section.
- FIG. 6. is a sectional drawing showing the pivoted base of the jack in FIG. 4.
- FIG. 8. is a view of the jack in FIG. 1 when folded.
- FIG. 9. is a partial perspective showing the barrel used in the invention in the slots of the support members.
- FIG. 10, 11 and 12 shows the back top section of the vehicle engaging section from FIG. 5.
- FIG. 13 is section II of FIG. 5.
- the screw threaded member (6) passes through a barrel or boss (8) set in the end of the arm (3) through closed slots (32) and is rotatably attached to the arm (1) near the base (4).
- the screw turns (6) in one direction the end of the arm in the barrel (8) is drawn towards the base (4) so that the load engaging member (5) is raised lifting the vehicle below which the jack is placed. Reverse rotation lowers the load engaging member (5).
- Arm (3) and (1) are channel shaped in cross-section.
- the base (4) is usually a channel shaped member as shown in FIG. 3A, 3B and 3C and will normally be made of metal as will arms (1) and (3).
- the rotatable member (5) is shown in FIG. 2 to be received in the partially circular recesses at the end of arm (3).
- the rotatable member (5) is normally cylindrical and the central part is larger than the ends (5a).
- the rotatable member is fixed into the walls of the profile of the arm (3) through sides of central part and is controlled lengthways in this way.
- the member (5) has stoppers (9a) to prevent the member rocking.
- This member (5) will preferably be made of a hard plastic material.
- FIGs, 3A, 3B and 3C sectional views are shown respectively of the lines CC. BB and AA on the jack in the area of the base (4) attached to the foot (1).
- the screw (6) extends towards the inside of the barrel (11) in which it turns freely and in which it is retained against longitudinal movement at least to the right by virtue of the cover (12). Outside the barrel (11) and on both sides there are two grooves inside which the edges of the recesses of the shoe side walls fit (4).
- thebarrel (11) functions pivotally to connect the end of the screw (6) to the lower end of the shoe (1) and the base (4). Each one can move freely in relation to one another. Consequently, with a single item important aspects of the assemly of the jack can be achieved.
- the kack when the kack is not in use, it can be completely wound down with the shoe (1) fitting into the channel section of arm (3).
- the cranked handle can then be pivoted to lie alongside arms (1) and (3).
- FIGs 4, 5, 6 and 7 show a second drawing of the jack in accordance with the invention. Certain of its features may be incorporated into the first embodiment already described and vice versa.
- the jack of this embodiment includes a first arm (15) and a second arm (16) both pivoted at point (17) connecting the arms (15) and (16) there is a threaded member (18) with a crank (19) on its free end.
- the other end of this screw threaded member is held in a bushing or barrel (20) retained in grooves (32) in arm (16).
- the screw threaded member is threaded through a bushing (21) set in a slot (32)at the top end of arm (15).
- both arms (15) and (16) are of the channel shaped cross-section.
- the jack can be lowered from the position in FIG. 4 to a closed position as in FIG. 7 where the arm (16) fits entirely into arm (15).
- the base at the end of arm (15) is constructed to accomodate the free end of the first arm (15) directly.
- FIG. 5 shows an enlarged drawing of the insertion placed at the top end of arm (16).
- This is a plastic molded insert which is partially rounded with thickened edges. These thickened edges are separated by a groove (28) into which the sill seam weld of a car can be fitted for alignment.
- the insert rests on the thickness of the cross-section of arm (16) and rims (23a) of the thickened areas flush with the outer edges (16a) of arm (16).
- FIG. 13 shows a view specially from section II of FIG. 5 when an insert is fitted as shown in FIG. 10.
- the thickened areas (23) take the load of the car body and offers sufficient resistance in all cases because it is perfectly embedded.
- the insert (23) is made of a plastic material preferably, it can be applied by pressure onto the upper end of the second member (16).
- FIG. 6 is a partially sectional view of the bottom of arm (15) showing the base (22) which is preferably made of a plastic material and normally channel shaped.
- the base (22) has two sides extending up inside the bottom of are (15). Projecting from those sides of the base (22) are snap-fit projections (24) which extend through corresponding apertures on arm (15). This means the base (22) can be assembled easily and can nevertheless rotate freely.
- the bottom of the arm (15) has a rounded end (25) and that the shoe (22) also has a rounded part.
- the jacking load is transferred to the ground through the base (22) through the abutment between (25) and (26) instead of through the projections (24).
- the curved surface (26) meets shoulders (27) on each side, both of the base (22) and the shoe (15) and designed to limit relative rotation between base (22) and arm (15).
- FIG. 7 shows the jack in FIG. 4 completely wound down where the cranked handle (19) can be turned to tighten the screw member (18) in the assembly to prevent rattling.
- barrel (21) is placed within the channel section (15) while it is being set in position and it can be seen that each side of the channel (15) has a slot with a recesss (31) which has a substantially circular segment attached to an elongated segment (32).
- the barrel (21) has a cylindrical part transverse to the arm (15) to receive and secure the screw rotatably. At each end of the cylindrical part (33) it has the enlarged section (21).
- the slots (31)-(32) avoid making the wings open to the outside because they are closed and contributes to the reinforcement of the arms, specially at the ends (15a) in FIGs. 1, 4, 7, 8 and 9. Thus this design achieves a sturdy, secure and simple assembly.
- FIGs. 1 and 8 as shown in one of the drawings in the letter it is a folded position from which the jack can be operated. This is particularly outstanding as a feature.
