Definitions

  • the object of this invention is to provide the rear legs of a childs high chair with wheels supported upon novel clamps that are readily attachable upon the lower ends of the rear legs of the chair and when in place serve to prevent restless movements of the child in the chair from tipping it over rearwardly with possible injury to the occupant of the prostrated chair.
  • a further object is to afford duplicate wheeled attachments for the rear legs of a childs high chair which not only prevent the chair from being tilted rearwardly, but also afford convenient means for progressively moving the chairin any direction either while occupied or vacant, and thus facilitate the easy transfer of the chair from one locality to another.
  • Figure 1 is a perspective View showing the improvement secured upon the rear legs of a high chair.
  • Fig. 2 is an enlarged and partlysectional side view of the improved safety attachment mounted upon and detachably secured to the lower portion of a rear leg of a high chair, and
  • Fig. 3 is a detached plan View of the improvement.
  • the chair 10 may be of any preferred design which provides a high seat for accommodation of a child and has legs 10 of sufficient length for supporting the seat and which are cylindric at and near their lower ends.
  • the improved safety-wheel device which in service is duplicated for connection with the two rear legs of the high chair, comprises the following details of construction.
  • a bracket-frame consisting mainly of a plate-metal piece which in blank form is 'substantially triangular in contour is provided, and preferably the metal blank is of resilient material.
  • the triangular plate-metal blank is bent midway between its ends a, as shown at b, the bend being curved so as to produce a substantially semicircular wall 11 and aiford two similar side plates 12,
  • the lower edge of the bracket-frame, con structed as described, is horizontal, and the curved Web 11 is disposed at or near a right angle thereto, as indicated in Fig. 2.
  • the ends a of the side plates 12 maybe rounded, as shown by dotted lines as to one plate in Fig. 2, and near the ends a the two side plates are transversely perforated at opposite points.
  • Acaster-wheel 13 is rotatably mounted upon a short journal-shaft 14, secured by its ends in the perforations formed in the ends at of the side plates 12.
  • a stay-bar 15 is secured by its ends in opposite perforations formed in the side plates 12, which bar serves to prevent the side plates from being drawn against the hub of the caster-Wheel13 by the adjustment of a clamping-bolt 16.
  • the bolt 16 passes loosely through opposite perforations in the side plates 12 at a point somewhat above the stay-bar 15, and whenin place the head thereof is in engagement with one of the side plates.
  • a nut 17 is mounted upon the projected screw-cut end of the bolt 16 after the bolt has been'inserted through the perforations in the side plates and by its adjustment may be forcibly pressed upon the opposite side plate 12, and thus coact with the bolt to contract the space between the side plates a proper degree.
  • bracket-frames of the duplicate safety-wheel devices In applying the bracket-frames of the duplicate safety-wheel devices upon the rear legs 10 of the chair 10 said legs are respectively slid down through the space afforded between the curved web-wall 11 and the body of the bolt 16 on one of the bracket-frames.
  • the extremity of the inserted leg 10 extends such a distan'cebelow the lower edge of the bracket-frame mounted thereon as will permit the leg to normally sustain the weight imposed upon it.
  • An attachable wheel for a chair-leg comprising a U shaped bracket-frame having resilient side walls, a wheel held to rotate between the ends of the bracket-frame, and a clamping-bolt adapted to compress the side walls of the bracket-frame upon a chair-leg whereon said frame is mounted.
  • An attachable wheel for a chair-1eg comprising a bracket-frame formed of a threecornered plate-metal blank, bent intermediately to provide two spaced side walls and a curved intervening web, a caster-wheel j ournaled between the opposite sides of the bracket-frame, a transverse stay-bar having its ends secured in the sides of the bracketframe near the Wheel,and a transverse clamping-bolt having a head and nut, that respectively bear upon the side walls of the bracketframe, said nut by adj ustment being adapted to clamp the bolt-head on the bracket-frame and compress the sides of said frame against a chair-leg upon which the bracket-frame is mounted.
