REMOVABLE SPEED REDUCER BUMP

RESSAUT ANTIVITESSE AMOVIBLE

English Abstract

ABSTRACT OF THE DISCLOSURE
A manufactured hump adapted to be removably installed
across a lane, road, street, or the like and thus forces the
drivers to reduce speed while running over it. This removable speed
reducer bump is characterized by a simple and inexpensive construction
and installation and it comprises an elongated body including opposite
lateral edge portion, and an intermediate bump portion extending
longitudinally of the body; the bump portion has a uniformly-curved,
convex outline of constant cross-section transversely of the elongated
body and the lateral edge portions extend laterally inward edgewise
from the opposite outer edges respectively of the pump portion.

Claims

THE EMBODIMENTS OF THE INVENTION IN WHICH AN EXCLUSIVE
PROPERTY OR PRIVILEGE IS CLAIMED, ARE DEFINED AS FOLLOWS:
1. A removable spaced reducer bump comprising:
an elongated body made of a relatively narrow metal plate and including
a pair of lateral edge portions longitudinally extending along the
transvsrsely-opposite sides of the narrow metal plate, a bump portion
extending intermediate the lateral edge portions longitudinally of
the narrow metal plate and having a uniformly-curved, convex outline
of constant cross-section transversely of the narrow metal plate, and
the lateral edge portions cooperatively forming a base underlying the
bump portion; and the lateral edge portions having anchoring bolt apertures
formed therein and underlying the bump portion for concealed positioning
of anchoring bolts attaching the elongated body on the ground.
2. A removable speed reducer bump as defined in claim
1, wherein the lateral edge portions extend edgewise toward each other
under the bump portion.
3. A removable pseed reducer bump as defined in claim
1, wherein the bump portion is formed with access apertures overlying
the anchoring bolt apertures and allowing access for readily screwing
or unscrewing of the anchoring bolts.
4. A removable speed reducer bump as defined in claim
1, wherein the bump portion includes traction ridges extending longi-
tudinally thereof on the convex top surface of the same and laterally
spaced from each other transversely of the bump portion and lateral edge
portions.
5. A removable speed reducer bump as defined in claim
1, wherein said elongated body includes a pair of latarally-opposite
outer edges, each cooperatively defined by edgewise and outward merging
of one of said lateral edge portions with a corresponding outer edge
portion of the bump portion.

6. A removable speed reducer bump as defined in claim
5, wherein the lateral edge portions extend edgewise toward each other
under the bump portion and form mounting flanges inward of said
laterally-opposite outer edges; the bump portion is formed with access
apertures overlying the anchoring bolt apertures and allowing access
for readily screwing or unscrewing of the anchoring bolts, and the
bump portion includes traction ridges extending longitudinally on the
convex top surface of the same and laterally spaced from each other
transversely of the bump portion and lateral edge portions.

Description

FIELD DF THE IN~ENlIQN
___
This invantion r~late~ to a manufacturad bump of tha
typn that i~ r~movably instQll~d tran~versely scross a lan~ road,
3tr~et, nr the lik~ to ~low down the traffic.
DESCRIPTION OF THE PRIOR_ART
The only mflnufactured bump of the abova typ~ that 1
known rsquire~ a trough, or the like rece~s, ln the ground to ba
recss3ad into lt and, thu~, b~ rHmovsd ~rom upward pro~action from
ths ground and hindrance 3uch a8 to ~ snsw plnw clnaring the anow
along the corr~3ponding lane, road, ~trsat, or tha like, Such bump
requires the making of such trough or slongatsd rscsgg ~or it~
presant~ sQms complexlty of conatruction and inst~llation to achl~ve
the de3irad pivoting in and out of the corresponding reces~, ond 193
to some extent,at the mercy of adver~0 we~thsr, snow~ ic~ and fro~t-
defrost action.
SUMM~RY OF T~HE INUENTIOH
It is a g~n0ral object Df the present invention to
provids a removoble 3peed raducer b~mp of thQ above type which i~
of ~imple and inexpensive construction and inst~llation and which
is readily removable ~or unhal~per0d po~sQge of a snow plow or ths
like where it i8 no~m~lly install~d.
It is an object o~ the presant invsntion to provide
a remov~bl~ speed reducer bump of the abov~ type~ which ia mada o~
plats metal for simple and in~xp~nsive construction~
It iB another object of the pr0sant inuantlon to
provide a removabla ~peed red wer bump of tha above typa, which i8
simply installsd by anchoring bolts with the latt~r oositinned in
conc~alment such that they do not intarfer0 with th~ tir0s of tha
vehiclae running ovar tha installsd bump.

which i~ illu~trated, by way of axample9 in the acoompanying drawing,
in which:
Figure 1 i8 a per~pectiv~ view o~ a re~ovable speed
reduc~r bump operatively in~talled acroR~ a driveway shown in
da~hed line~; and
Figurs 2 is a tran~varge oross-aection through the
r~mo~able speed rsducHr bump of Figu~e 1.
The illustrated removsble 3pe~d radu~r bump lU t~k~e
the form of an elongated body mad0 ~rom ~ relativ~ly n~rrow metal
plate. The bump 10 incluoes a pair o~ laterally-oppo~ite side
portions 11 and an intermediate bump portion 12, all longit~dinally
extending lengthwi~H o~ the 010ngated body and transversely od~oining
one anothar. Th0 interm0diate bump portion 12 has a uni~ormly-
curvad, conv0x outl~ne of ~on3tant cro~s~acction tran~versely of the
bump. The intermsdiate bump portiun 12 defin0s a psir o~ laterally-
opposite outer edges 13. The lateral edge pùrtion~ lllater~lly
extend edgewiss toward e~ch oth~r and are Plat in the ~am0 plan~,
thus ~orming a ba~e Por the bump. The lateral 0dge porti~ne 11
form mounting flange~ inward of th~ later&lly-oppo~ite ~ter ed~
13. Tha latsral Hdge p~rtion~ 11 merge edgewi~e laterally outward with
the corresponding out~r lateral edges o~ the intermediata bump portion
12. Thu~, the latter completely overlies both lateral edgs portions
11.
Th0 ba~a and, more specifically, tha oppo~ita l~terel
edge portiona 11 ara providad each wlth a row of apertures in ea~
of which i9 po~itiDned an anchor bolt 14. Those anchor bolts 14 aEe
removably threaded in anchoring nuts 15 ~ix0dly s~nk in the ground
in apprDpri~te po~ition to regiater with the anchoring bolt aperturea,
Ths intermsdiata bump portion 12 i3 provided with acc389 aparture 16
overlying the anchoring bolt aperturs3 to provid~ accaa~ ~or screwing
and un~cr~wing of th~ anchsring bolts~l4.
Traction ridges 17 ~xtend longitdinally Df the bump nn
its conv0x top ~urfac~ and ara lat3rally ~pacad from each oth~r
