Stand for baby seat

Abstract

A stand for baby seat particularly useful on the back of a lawn mower tractor. The stand comprises a sliding plate at its lower end and a square tube on its upper end. The sliding plate slips into a sleeve fixed on the rear end of the tractor, for that purpose. The square tube receives one end of a positioning tube, adjustable in the square tube. The other end of the positioning tube supports a horizontal plate on which is fixed the baby seat. The baby is then in a position near an adult driver, immediately to the right, to the left or to the back of the driver.

[0008] U.S. Pat. No. 5,700,059, Moscot, Dec. 23, 1997, is a baby support simulating the way one generally holds a baby.

OBJECTS AND ADVANTAGES

[0009] It is a general objective of the invention to provide a stand allowing the installation of baby seats on motorized vehicles such as small tractors. A more precise objective is to provide a sliding sleeve fixed on the back of a tractor, a sleeve that receives a plate with an L-shaped support arm mounted thereon. A support arm the top thereof holding an extension square tubing which receives a sliding arm that supports a baby seat. A stand apparatus that can be fixed in many ways, for example, on the back, on either side of the driver, or accommodating two seats on the back, on the left or right sides.

DESCRIPTION OF THE PREFERRED EMBODIMENT

[0016] In the description which follows and the drawings which accompany it similar numbers refer to identical parts in the various figures.

[0017] FIG. 1 shows a stand 20 ready to use, with a back seat 22, shown in dotted line. Seen from the back, the stand 20 has a T-shape. At its bottom is a plate 24 sliding into a sleeve 26 fixed by fixation screws 40, on a lower portion, at the back of a tractor 28—the rear part of it shown in dotted line—. The sleeve 26 has rectangular edges 76, for parallel entry, or at least forming an acute direction; a blocking screw 78 maintains the plate 24 in the sleeve 26. At the upper part of the stand 20 is a square tube 30 equipped with locking pins 32. A positioning tube 34 slips in the square tube 30 and is locked in place by the locking pins 32. A plate 36 is fixed at one end of the positioning tube 34 by positioning screws 38. The plate 36 receives the seat 22 and fixes it firmly and securely. The plate 24 must have parallel sides and preferably must be a rectangular plate 76.

[0018] FIG. 2 shows the stand 20 installed on a side wall 28′ of the tractor 28. The stand 20 has an L-shaped arm to keep the seat 22 away from the tractor 28 and at a certain height within grasp by the driver parent. The sleeve 26 is fixed by fixation screws 40 onto the rear end of the tractor 28′. The sliding plate 24 is slipped into the sleeve 26. The sliding plate 24 is tilted according to an angle &mgr; 70 with respect to the stand 20 so that the stand 20 and thus the seat be maintained straight up despite the slant of the tractor side. The locking pins 32 fix the positioning tube 34 in place in the square tube 30. The locking pin 32 has a head 44. A fastener 42 passes through the head 44 of the pin 32 then through the positioning tube 34 and ties itself at the other end of the pin 32 to prevent the pin 32 from being shaken off.

[0019] FIG. 3 is a top view of the stand 20. The plate 36, rectangular, is fixed on one of the long sides of the positioning tube 34. The plate 36 has small screw holes 72. There are four positioning screws 38, one at each corner of plate 36 to fix the seat on the apparatus. The same applies for the sleeve 26, which has four sleeve holes 46 to receive the fixation screws 40. As for the square tube 30, it has two tubes holes 48 to receive the locking pins 32. One also notices the shape of the fastener 42 which has a loop 50 which passes through the head of a locking pin 32.

[0020] FIG. 4 illustrates the way in which the seat 22 is installed on the plate 36. There are two sizes of positioning screws 38. Two long screws 52, at the back, pass through the seat 22, the plate 36 and the positioning tube 34. Two short screws 54, on the front, pass through the seat 22 and the plate 36. The plate 36 shows a collar 56 under the holes that accommodates a short screw and prevents the play of the short screw.

[0021] FIG. 5 shows stand 20 in totality. One notices that the plate 36 is fixed on the end of the positioning tube 34 with long screws 52. One also sees two short screws 54 in small screw holes 72 and two long screws 52 in long screw holes 74. One also sees an L-shaped stand with a riser 60 and a horizontal dormant 62 terminated by the sliding plate 24 fixed onto the sleeve 26 by means of fixation screws 40. One also sees the interior 64 of the square tube 30.

OTHER EMBODIMENTS

[0022] The positioning tube is made so that plate 36 can be fixed on either side of the square tube 30 so that the seat 22 can be installed at the left or the right of the stand 20.

[0023] Another embodiment comprises two plates 36 fixed at the ends on a flat part of the positioning tube 34, which makes it possible to fix two seats on the support stand. The positioning tube 34 matches in square tube 30 thanks to a flat part on the top, that which prevents rotation of the plate 36. The tube 30 need not be square in section but must have at least one flat part and preferably two rectangular flat parts such as an L beam, or three flat parts as for matching a U beam, the positioning tube 34 having corresponding matching sections. It is clearly understood that the embodiments of this invention which were described above, in reference to the annexed drawing, were given as an indication and are by no means restrictive. Modifications and adaptations can be made without deviating from the scope of this invention. Other embodiments are possible and are limited only by the scope of the claims which follow:
